Design Tokens

Generate type scales, color palettes, spacing systems, and dark mode derivations with math — not guessing. Includes WCAG contrast checking, systematic spacing grids, and production-ready CSS/Tailwind output.

When to Use

User is setting up a new project's design system
User asks for a type scale, color palette, or spacing system
User needs WCAG-compliant color combinations
User wants dark mode colors derived from a light palette
User asks for "design tokens" or "theme setup"
Building a Tailwind config or CSS custom properties

Core Philosophy

Math over taste. Scales should follow ratios, not arbitrary values.
Accessibility by default. Every text/background combo must pass WCAG AA.
Systematic. Every value should be derivable from a base + ratio.
Portable. Output as CSS custom properties, Tailwind config, or JSON tokens.

Type Scale Generation

The Formula

fontSize = baseFontSize × ratio^step

Recommended Ratios

Ratio	Name	Value	Best for
Minor Second	1.067	Tight, minimal difference	Dense UI, dashboards
Major Second	1.125	Subtle progression	Apps, data-heavy interfaces
Minor Third	1.200	Balanced, versatile	Most websites, SaaS
Major Third	1.250	Clear hierarchy	Marketing sites, blogs
Perfect Fourth	1.333	Strong contrast	Editorial, landing pages
Augmented Fourth	1.414	Dramatic	Bold designs, portfolios
Perfect Fifth	1.500	Very dramatic	Hero-heavy designs

Generating the Scale

Given a base size (typically 16px) and a ratio:

Step -2: 16 / ratio² = xs
Step -1: 16 / ratio  = sm
Step  0: 16          = base
Step  1: 16 × ratio  = lg
Step  2: 16 × ratio² = xl
Step  3: 16 × ratio³ = 2xl
Step  4: 16 × ratio⁴ = 3xl
Step  5: 16 × ratio⁵ = 4xl
Step  6: 16 × ratio⁶ = 5xl

Round to nearest 0.5px or convert to rem (÷ 16).

Line Height Rules

Font Size	Line Height	Use
≤ 14px	1.6–1.7	Small text, captions
16–20px	1.5–1.6	Body text
20–32px	1.3–1.4	Subheadings
32–48px	1.1–1.2	Headings
48px+	1.0–1.1	Display/hero text

Rule of thumb: As font size increases, line height decreases.

Letter Spacing Rules

Size	Letter Spacing	Why
Small text (≤14px)	`0.01–0.02em`	Slightly open for readability
Body text	`0em` (normal)	Don't touch it
Subheadings	`-0.01em`	Slightly tighten
Headings	`-0.02em` to `-0.03em`	Tighten as size grows
Display text	`-0.03em` to `-0.05em`	Tight tracking at large sizes

Font Weight Pairing

Role	Weight	Tailwind
Body	400 (Regular)	`font-normal`
Body emphasis	500 (Medium)	`font-medium`
Subheading	600 (Semibold)	`font-semibold`
Heading	700 (Bold)	`font-bold`
Display	800 (Extrabold)	`font-extrabold`

Output Example (CSS Custom Properties)

:root {
  --font-size-xs: 0.694rem;    /* 11.1px */
  --font-size-sm: 0.833rem;    /* 13.3px */
  --font-size-base: 1rem;      /* 16px */
  --font-size-lg: 1.2rem;      /* 19.2px */
  --font-size-xl: 1.44rem;     /* 23px */
  --font-size-2xl: 1.728rem;   /* 27.6px */
  --font-size-3xl: 2.074rem;   /* 33.2px */
  --font-size-4xl: 2.488rem;   /* 39.8px */
  --font-size-5xl: 2.986rem;   /* 47.8px */
}

Color Palette Generation

Step 1: Choose Base Colors

Every palette needs:

Token	Purpose	Example
`primary`	Main brand color, CTAs	Your brand color
`neutral`	Text, borders, backgrounds	Gray (warm/cool/pure)
`success`	Positive states	Green
`warning`	Caution states	Amber/yellow
`error`	Destructive states	Red
`info`	Informational	Blue (can overlap primary)

Step 2: Generate Shade Scale (50–950)

For each base color, generate a 10-step shade scale. The base color is typically the 500 step.

Method: HSL manipulation

Starting from the base HSL:

Step	Lightness Adjustment	Saturation Adjustment
50	+45%	-30%
100	+38%	-25%
200	+28%	-15%
300	+18%	-5%
400	+8%	0%
500	0% (base)	0% (base)
600	-8%	+5%
700	-18%	+5%
800	-28%	0%
900	-38%	-10%
950	-45%	-20%

Clamp all values: lightness 0–100%, saturation 0–100%.

Step 3: Semantic Token Mapping

Map shade steps to semantic roles:

/* Light mode */
--color-bg: var(--neutral-50);
--color-bg-subtle: var(--neutral-100);
--color-bg-muted: var(--neutral-200);
--color-border: var(--neutral-200);
--color-border-strong: var(--neutral-300);
--color-text-muted: var(--neutral-500);
--color-text-subtle: var(--neutral-600);
--color-text: var(--neutral-900);
--color-text-heading: var(--neutral-950);

--color-primary: var(--primary-600);
--color-primary-hover: var(--primary-700);
--color-primary-bg: var(--primary-50);
--color-primary-text: white;

WCAG Contrast Checking

The Formula

Contrast ratio = (L1 + 0.05) / (L2 + 0.05)

Where L1 = lighter relative luminance, L2 = darker.

Relative Luminance

For each channel (R, G, B):
  sRGB = channel / 255
  linear = sRGB <= 0.04045 ? sRGB / 12.92 : ((sRGB + 0.055) / 1.055) ^ 2.4

L = 0.2126 × R_linear + 0.7152 × G_linear + 0.0722 × B_linear

WCAG Requirements

Level	Ratio	Applies to
AA Normal Text	≥ 4.5:1	Body text (< 18px or < 14px bold)
AA Large Text	≥ 3:1	≥ 18px regular or ≥ 14px bold
AAA Normal Text	≥ 7:1	Enhanced accessibility
AA UI Components	≥ 3:1	Borders, icons, focus rings

Quick Reference (Neutral on White #FFFFFF)

Shade	Approx Contrast	Passes
300	~2.5:1	❌ Decorative only
400	~3.5:1	✅ Large text, UI
500	~4.5:1	✅ AA body text
600	~6:1	✅ AA comfortable
700	~8:1	✅ AAA body text

Checking Contrast Programmatically

When generating palettes, always verify:

text (900) on bg (50) → must be ≥ 4.5:1
text-muted (500) on bg (50) → must be ≥ 4.5:1
primary (600) on white → must be ≥ 4.5:1
primary-text on primary (600) → must be ≥ 4.5:1
border (200) on bg (50) → must be ≥ 3:1

If a combo fails, adjust the darker color one step darker until it passes.

Spacing System

Base-4 Scale (Recommended)

Everything is a multiple of 4px. Predictable, consistent, works with most font sizes.

:root {
  --space-0: 0px;
  --space-0.5: 2px;
  --space-1: 4px;
  --space-1.5: 6px;
  --space-2: 8px;
  --space-3: 12px;
  --space-4: 16px;
  --space-5: 20px;
  --space-6: 24px;
  --space-8: 32px;
  --space-10: 40px;
  --space-12: 48px;
  --space-16: 64px;
  --space-20: 80px;
  --space-24: 96px;
  --space-32: 128px;
}

This matches Tailwind's default scale exactly.

Spacing Usage Guide

Context	Spacing	Values
Inline icon gap	space-1 to space-2	4–8px
Button padding	space-2 × space-4	8px 16px
Card padding	space-4 to space-6	16–24px
Section gap (between elements)	space-6 to space-8	24–32px
Section padding (container)	space-12 to space-16	48–64px
Page section vertical rhythm	space-16 to space-24	64–96px

The Container Width Scale

Token	Width	Use
`sm`	640px	Narrow content (auth forms)
`md`	768px	Blog posts, documentation
`lg`	1024px	App layouts
`xl`	1280px	Wide layouts
`2xl`	1536px	Full-width dashboards

Dark Mode Derivation

The Inversion Pattern

Don't manually pick dark mode colors. Derive them systematically:

Light mode          →  Dark mode
neutral-50  (bg)    →  neutral-950 (bg)
neutral-100 (bg-subtle) → neutral-900 (bg-subtle)
neutral-200 (border) → neutral-800 (border)
neutral-300 (border-strong) → neutral-700 (border-strong)
neutral-500 (text-muted) → neutral-400 (text-muted)
neutral-600 (text-subtle) → neutral-300 (text-subtle)
neutral-900 (text)  →  neutral-50  (text)
neutral-950 (heading) → neutral-50 (heading)

The rule: Background shades flip (50↔950, 100↔900, 200↔800). Text shades flip similarly. Middle shades (400–600) shift by ~1–2 steps.

Primary Color in Dark Mode

Use a lighter step: primary-400 or primary-500 instead of primary-600
Reduce saturation slightly for dark backgrounds (avoids eye strain)
Verify contrast against neutral-900 or neutral-950 background

Semantic Tokens for Dark Mode

/* Light */
:root {
  --color-bg: var(--neutral-50);
  --color-text: var(--neutral-900);
  --color-primary: var(--primary-600);
}

/* Dark */
.dark {
  --color-bg: var(--neutral-950);
  --color-text: var(--neutral-50);
  --color-primary: var(--primary-400);
}

The beauty: components reference semantic tokens, never raw shades. Switching themes is just swapping the token mapping.

      },
      colors: {
        primary: {
          50: 'hsl(220, 50%, 95%)',
          500: 'hsl(220, 80%, 50%)',
          900: 'hsl(220, 60%, 15%)',
        },
      },
    },
  },
}

JSON Design Tokens (W3C Format)

{
  "color": {
    "primary": {
      "500": { "$value": "hsl(220, 80%, 50%)", "$type": "color" }
    }
  },
  "fontSize": {
    "base": { "$value": "1rem", "$type": "dimension" }
  }
}

Step-by-Step: Full Design Token Setup

Ask: What's the project? (marketing site, SaaS app, dashboard?)
Type scale: Pick ratio based on project type → generate scale
Colors: Get brand color → generate shade scales for primary + neutral + semantic
Verify contrast: Check all text/bg combos against WCAG AA
Spacing: Use base-4 scale (match Tailwind)
Dark mode: Derive from light palette using inversion pattern
Output: Generate CSS custom properties and/or Tailwind config

Examples

Example 1: "Set up design tokens for a SaaS dashboard"

Type: Minor Third (1.2) ratio, 16px base — clear hierarchy without being dramatic
Colors: Generate from brand blue, warm gray neutral
Spacing: Base-4 (Tailwind default)
Dark mode: Full derivation

Example 2: "I need a color palette from this brand color: #6366F1"

Parse HSL: ~239°, 84%, 67%
Generate 50–950 scale using the shade generation method
Map semantic tokens
Verify WCAG contrast for all text/bg combos
Output as CSS + Tailwind config

Example 3: "Create a type scale for a blog"

Ratio: Major Third (1.25) — strong hierarchy for editorial content
Base: 18px (slightly larger for long-form reading)
Generate scale with line-height and letter-spacing for each step

## Type Scale Generation

### The Formula

```
fontSize = baseFontSize × ratio^step
```

### Recommended Ratios

| Ratio | Name | Value | Best for |
|-------|------|-------|----------|
| Minor Second | 1.067 | Tight, minimal difference | Dense UI, dashboards |
| Major Second | 1.125 | Subtle progression | Apps, data-heavy interfaces |
| Minor Third | 1.200 | Balanced, versatile | Most websites, SaaS |
| Major Third | 1.250 | Clear hierarchy | Marketing sites, blogs |
| Perfect Fourth | 1.333 | Strong contrast | Editorial, landing pages |
| Augmented Fourth | 1.414 | Dramatic | Bold designs, portfolios |
| Perfect Fifth | 1.500 | Very dramatic | Hero-heavy designs |

### Generating the Scale

Given a base size (typically 16px) and a ratio:

```
Step -2: 16 / ratio² = xs
Step -1: 16 / ratio  = sm
Step  0: 16          = base
Step  1: 16 × ratio  = lg
Step  2: 16 × ratio² = xl
Step  3: 16 × ratio³ = 2xl
Step  4: 16 × ratio⁴ = 3xl
Step  5: 16 × ratio⁵ = 4xl
Step  6: 16 × ratio⁶ = 5xl
```

Round to nearest 0.5px or convert to rem (÷ 16).

### Line Height Rules

| Font Size | Line Height | Use |
|-----------|-------------|-----|
| ≤ 14px | 1.6–1.7 | Small text, captions |
| 16–20px | 1.5–1.6 | Body text |
| 20–32px | 1.3–1.4 | Subheadings |
| 32–48px | 1.1–1.2 | Headings |
| 48px+ | 1.0–1.1 | Display/hero text |

**Rule of thumb:** As font size increases, line height decreases.

### Letter Spacing Rules

| Size | Letter Spacing | Why |
|------|---------------|-----|
| Small text (≤14px) | `0.01–0.02em` | Slightly open for readability |
| Body text | `0em` (normal) | Don't touch it |
| Subheadings | `-0.01em` | Slightly tighten |
| Headings | `-0.02em` to `-0.03em` | Tighten as size grows |
| Display text | `-0.03em` to `-0.05em` | Tight tracking at large sizes |

### Font Weight Pairing

| Role | Weight | Tailwind |
|------|--------|----------|
| Body | 400 (Regular) | `font-normal` |
| Body emphasis | 500 (Medium) | `font-medium` |
| Subheading | 600 (Semibold) | `font-semibold` |
| Heading | 700 (Bold) | `font-bold` |
| Display | 800 (Extrabold) | `font-extrabold` |

### Output Example (CSS Custom Properties)

```css
:root {
  --font-size-xs: 0.694rem;    /* 11.1px */
  --font-size-sm: 0.833rem;    /* 13.3px */
  --font-size-base: 1rem;      /* 16px */
  --font-size-lg: 1.2rem;      /* 19.2px */
  --font-size-xl: 1.44rem;     /* 23px */
  --font-size-2xl: 1.728rem;   /* 27.6px */
  --font-size-3xl: 2.074rem;   /* 33.2px */
  --font-size-4xl: 2.488rem;   /* 39.8px */
  --font-size-5xl: 2.986rem;   /* 47.8px */
}
```

## Color Palette Generation

### Step 1: Choose Base Colors

Every palette needs:

| Token | Purpose | Example |
|-------|---------|---------|
| `primary` | Main brand color, CTAs | Your brand color |
| `neutral` | Text, borders, backgrounds | Gray (warm/cool/pure) |
| `success` | Positive states | Green |
| `warning` | Caution states | Amber/yellow |
| `error` | Destructive states | Red |
| `info` | Informational | Blue (can overlap primary) |

### Step 2: Generate Shade Scale (50–950)

For each base color, generate a 10-step shade scale. The base color is typically the 500 step.

**Method: HSL manipulation**

Starting from the base HSL:

| Step | Lightness Adjustment | Saturation Adjustment |
|------|---------------------|----------------------|
| 50 | +45% | -30% |
| 100 | +38% | -25% |
| 200 | +28% | -15% |
| 300 | +18% | -5% |
| 400 | +8% | 0% |
| 500 | 0% (base) | 0% (base) |
| 600 | -8% | +5% |
| 700 | -18% | +5% |
| 800 | -28% | 0% |
| 900 | -38% | -10% |
| 950 | -45% | -20% |

Clamp all values: lightness 0–100%, saturation 0–100%.

### Step 3: Semantic Token Mapping

Map shade steps to semantic roles:

```css
/* Light mode */
--color-bg: var(--neutral-50);
--color-bg-subtle: var(--neutral-100);
--color-bg-muted: var(--neutral-200);
--color-border: var(--neutral-200);
--color-border-strong: var(--neutral-300);
--color-text-muted: var(--neutral-500);
--color-text-subtle: var(--neutral-600);
--color-text: var(--neutral-900);
--color-text-heading: var(--neutral-950);

--color-primary: var(--primary-600);
--color-primary-hover: var(--primary-700);
--color-primary-bg: var(--primary-50);
--color-primary-text: white;
```

---

## WCAG Contrast Checking

### The Formula

Contrast ratio = (L1 + 0.05) / (L2 + 0.05)

Where L1 = lighter relative luminance, L2 = darker.

### Relative Luminance

```
For each channel (R, G, B):
  sRGB = channel / 255
  linear = sRGB <= 0.04045 ? sRGB / 12.92 : ((sRGB + 0.055) / 1.055) ^ 2.4

L = 0.2126 × R_linear + 0.7152 × G_linear + 0.0722 × B_linear
```

### WCAG Requirements

| Level | Ratio | Applies to |
|-------|-------|-----------|
| AA Normal Text | ≥ 4.5:1 | Body text (< 18px or < 14px bold) |
| AA Large Text | ≥ 3:1 | ≥ 18px regular or ≥ 14px bold |
| AAA Normal Text | ≥ 7:1 | Enhanced accessibility |
| AA UI Components | ≥ 3:1 | Borders, icons, focus rings |

### Quick Reference (Neutral on White #FFFFFF)

| Shade | Approx Contrast | Passes |
|-------|-----------------|--------|
| 300 | ~2.5:1 | ❌ Decorative only |
| 400 | ~3.5:1 | ✅ Large text, UI |
| 500 | ~4.5:1 | ✅ AA body text |
| 600 | ~6:1 | ✅ AA comfortable |
| 700 | ~8:1 | ✅ AAA body text |

### Checking Contrast Programmatically

When generating palettes, always verify:
1. `text` (900) on `bg` (50) → must be ≥ 4.5:1
2. `text-muted` (500) on `bg` (50) → must be ≥ 4.5:1
3. `primary` (600) on `white` → must be ≥ 4.5:1
4. `primary-text` on `primary` (600) → must be ≥ 4.5:1
5. `border` (200) on `bg` (50) → must be ≥ 3:1

If a combo fails, adjust the darker color one step darker until it passes.

## Spacing System

### Base-4 Scale (Recommended)

Everything is a multiple of 4px. Predictable, consistent, works with most font sizes.

```css
:root {
  --space-0: 0px;
  --space-0.5: 2px;
  --space-1: 4px;
  --space-1.5: 6px;
  --space-2: 8px;
  --space-3: 12px;
  --space-4: 16px;
  --space-5: 20px;
  --space-6: 24px;
  --space-8: 32px;
  --space-10: 40px;
  --space-12: 48px;
  --space-16: 64px;
  --space-20: 80px;
  --space-24: 96px;
  --space-32: 128px;
}
```

This matches Tailwind's default scale exactly.

### Spacing Usage Guide

| Context | Spacing | Values |
|---------|---------|--------|
| Inline icon gap | space-1 to space-2 | 4–8px |
| Button padding | space-2 × space-4 | 8px 16px |
| Card padding | space-4 to space-6 | 16–24px |
| Section gap (between elements) | space-6 to space-8 | 24–32px |
| Section padding (container) | space-12 to space-16 | 48–64px |
| Page section vertical rhythm | space-16 to space-24 | 64–96px |

### The Container Width Scale

| Token | Width | Use |
|-------|-------|-----|
| `sm` | 640px | Narrow content (auth forms) |
| `md` | 768px | Blog posts, documentation |
| `lg` | 1024px | App layouts |
| `xl` | 1280px | Wide layouts |
| `2xl` | 1536px | Full-width dashboards |

## Dark Mode Derivation

### The Inversion Pattern

Don't manually pick dark mode colors. Derive them systematically:

```
Light mode          →  Dark mode
neutral-50  (bg)    →  neutral-950 (bg)
neutral-100 (bg-subtle) → neutral-900 (bg-subtle)
neutral-200 (border) → neutral-800 (border)
neutral-300 (border-strong) → neutral-700 (border-strong)
neutral-500 (text-muted) → neutral-400 (text-muted)
neutral-600 (text-subtle) → neutral-300 (text-subtle)
neutral-900 (text)  →  neutral-50  (text)
neutral-950 (heading) → neutral-50 (heading)
```

**The rule:** Background shades flip (50↔950, 100↔900, 200↔800). Text shades flip similarly. Middle shades (400–600) shift by ~1–2 steps.

### Primary Color in Dark Mode

- Use a lighter step: `primary-400` or `primary-500` instead of `primary-600`
- Reduce saturation slightly for dark backgrounds (avoids eye strain)
- Verify contrast against `neutral-900` or `neutral-950` background

### Semantic Tokens for Dark Mode

```css
/* Light */
:root {
  --color-bg: var(--neutral-50);
  --color-text: var(--neutral-900);
  --color-primary: var(--primary-600);
}

/* Dark */
.dark {
  --color-bg: var(--neutral-950);
  --color-text: var(--neutral-50);
  --color-primary: var(--primary-400);
}
```

The beauty: components reference semantic tokens, never raw shades. Switching themes is just swapping the token mapping.

### Tailwind Config

```js
module.exports = {
  theme: {
    extend: {
      fontSize: {
        'xs': '0.694rem',
        'sm': '0.833rem',
        'base': '1rem',
        'lg': '1.2rem',
        'xl': '1.44rem',
      },
      colors: {
        primary: {
          50: 'hsl(220, 50%, 95%)',
          500: 'hsl(220, 80%, 50%)',
          900: 'hsl(220, 60%, 15%)',
        },
      },
    },
  },
}
```

### JSON Design Tokens (W3C Format)

```json
{
  "color": {
    "primary": {
      "500": { "$value": "hsl(220, 80%, 50%)", "$type": "color" }
    }
  },
  "fontSize": {
    "base": { "$value": "1rem", "$type": "dimension" }
  }
}
```

## Step-by-Step: Full Design Token Setup

1. **Ask:** What's the project? (marketing site, SaaS app, dashboard?)
2. **Type scale:** Pick ratio based on project type → generate scale
3. **Colors:** Get brand color → generate shade scales for primary + neutral + semantic
4. **Verify contrast:** Check all text/bg combos against WCAG AA
5. **Spacing:** Use base-4 scale (match Tailwind)
6. **Dark mode:** Derive from light palette using inversion pattern
7. **Output:** Generate CSS custom properties and/or Tailwind config

## Examples

### Example 1: "Set up design tokens for a SaaS dashboard"

- Type: Minor Third (1.2) ratio, 16px base — clear hierarchy without being dramatic
- Colors: Generate from brand blue, warm gray neutral
- Spacing: Base-4 (Tailwind default)
- Dark mode: Full derivation

### Example 2: "I need a color palette from this brand color: #6366F1"

- Parse HSL: ~239°, 84%, 67%
- Generate 50–950 scale using the shade generation method
- Map semantic tokens
- Verify WCAG contrast for all text/bg combos
- Output as CSS + Tailwind config

### Example 3: "Create a type scale for a blog"

- Ratio: Major Third (1.25) — strong hierarchy for editorial content
- Base: 18px (slightly larger for long-form reading)
- Generate scale with line-height and letter-spacing for each step
