Palette Builder

Generate accessible color systems with semantic design tokens for websites, apps, and design systems.
Start from your brand color, check contrast and color blindness, and export 56 tokens for CSS, Tailwind, JSON, and AI coding workflows.

HOW IT WORKS

How to Use Palette Builder

Go from your brand color to a production-ready semantic color system in five steps.

  1. 1

    Start from your brand color

    Paste your brand hex to build the whole system around it, pick one of 14 ready-made presets, or choose a color family and let the generator roll.

  2. 2

    Set the mood

    Choose Professional, Bold, Friendly, Premium, or Minimal to control saturation, contrast, and overall visual tone.

  3. 3

    Tune the accent and the greys

    Decide how far your accent sits from the brand color, and pick cool, plain, warm, or brand-tinted neutrals for backgrounds, cards, borders, and text.

  4. 4

    Check readability

    Nine checks cover body text, links, buttons, card and input edges, focus rings, and color blindness. Anything that falls short is named, and one click fixes it.

  5. 5

    Export your tokens

    Export 56 tokens — roles, status colors, and full 50–950 scales with dark values — as CSS variables, Tailwind config, JSON, AI prompts, or palette files.

WHY PALETTE BUILDER

More Than a Basic Color Palette Generator

Most palette tools generate random colors. Palette Builder creates complete semantic color systems with full color scales, accessibility validation, design token exports, and AI-ready workflows.

Semantic Color System

Generate role-based tokens like primary, secondary, accent, background, surface, and text — each backed by a full 50–950 scale instead of a single flat hex.

Neutrals That Look Like Real Products

Backgrounds, cards, borders, and text are built from a proper grey — cool, plain, warm, or tinted with your brand — the way real design systems ship them.

Personality and Accent Control

Apply Professional, Bold, Friendly, Premium, or Minimal modes, then choose how far your accent sits from the brand color — from the same hue to its opposite.

Accessibility Built In

Nine checks cover text, links, buttons, card and input edges, focus rings, and color blindness — each judged against its own WCAG threshold, with a one-click fix.

Real-World Preview System

Preview your palette across desktop dashboards, mobile interfaces, UI components, illustrations, and role maps — and see it as a color-blind viewer does.

Developer-Ready Exports

Export 56 tokens — roles, status colors, and full scales with dark values — as CSS variables, Tailwind config, JSON, AI prompts, and palette files.

Unlike generic color pickers, Palette Builder generates accessible semantic color systems built for modern design systems and AI-assisted frontend development.

Palette Builder FAQ

Common questions about semantic color systems, families, neutrals, accessibility, and exporting palettes.

What is a semantic color system?
A semantic color system uses role-based color tokens such as primary, secondary, accent, background, surface, and text instead of hardcoded hex values. This makes interfaces easier to maintain, scale, and reuse across products.
How is Palette Builder different from a basic color palette generator?
Most palette tools generate visually pleasing colors only. Palette Builder creates complete semantic color systems with accessibility validation, live UI previews, and developer-ready exports for production workflows.
What are color families in Palette Builder?
Color families are curated hue groups such as Blue, Green, Purple, Teal, Orange, and Neutral. Each family includes multiple tuned variants to generate consistent brand and neutral color scales.
What are personality modes?
Personality modes control the visual character of the palette. Professional creates balanced systems, Bold increases contrast and saturation, Friendly feels softer, Premium feels refined, and Minimal reduces visual noise.
How does the readability check work?
Nine checks run on every palette: body text, secondary text, links, button labels, accent highlights, card edges, input edges, focus rings, and color blindness. Each pair is judged against its own WCAG threshold rather than a single blanket number, because a card edge and body text are not held to the same standard. Anything that falls short is named in plain words, and the Fix contrast button repairs it.
Why is my background grey instead of a tint of my brand color?
Because that is what real products do. Tailwind, shadcn, GitHub, and Stripe all pair a brand color with a grey chosen independently of it — usually a slightly cool grey. Palette Builder defaults to the same, and the Neutrals control lets you pick cool, plain, warm, or brand-tinted greys if a colored page is what you want.
What does the Accent setting do?
It sets how far your accent color sits from your brand color: the same hue, nearby, balanced, three-way, or opposite. The tool also checks that the two stay distinguishable for someone with color blindness, and separates them by lightness if the hues alone are not enough.
Does Palette Builder check for color blindness?
Yes. Every palette is measured for how distinguishable your primary and accent are under deuteranopia, protanopia, and tritanopia, and the preview can be viewed as each of those. Hue distance alone does not solve color blindness, so the generator separates colors by lightness when it has to.
What is the difference between brand and neutral scales?
Brand scales generate the primary visual identity colors used for buttons, highlights, and CTAs. Neutral scales generate background, surface, border, and text colors used to build readable interfaces. Both ship as full 50–950 scales, so you can build hover, pressed, and disabled states from the same system.
Can I export Palette Builder results for development?
Yes. Every palette exports 56 tokens — the eight roles, four status colors, and the full 50–950 scales behind them, with dark-theme values where they differ — as CSS variables, Tailwind configuration, JSON tokens, AI prompts, and palette files.
Can I build a palette around my own brand color?
Yes. Paste your brand hex and it becomes the primary exactly, not an approximation. It is locked automatically, so Generate re-rolls everything else around it while your brand color stays put.
Can I use Palette Builder with AI coding tools?
Yes. Palette Builder is designed for AI-assisted frontend workflows and can export structured color tokens and AI-ready instructions for tools like Claude, Cursor, ChatGPT, and similar coding assistants.
