High-contrast accessible color choices ensure seamless UI/UX readability. This generator computes mathematical harmonies in your browser and verifies accessibility standards instantaneously.

How to use it

How to use it

  1. Step 1

    Choose Base Color or Upload Image

    Select a HEX color or click Extract from Photo to upload an image.
  2. Step 2

    Inspect Contrast & UI Mockup

    Check the WCAG score and preview color mappings in the interactive website mockup.
  3. Step 3

    Export Design Tokens

    Download CSS, Tailwind, Flutter, or Figma JSON tokens with one click.

Accessibility & WCAG Contrast Inspection

Every swatch automatically calculates its WCAG contrast ratio against white and black text, ensuring compliance with AA/AAA accessibility standards for mobile and web apps.

Real-Time Interactive Component Mockup Preview

Preview your solid color scheme in real time across simulated web navigation headers, hero cards, action call-to-action buttons, and mobile dashboards.

Color Blindness Simulation Engine

Test how your palette appears to users with Protanopia, Deuteranopia, or Tritanopia color vision deficiencies.

Benefits

  • No registration required.
  • Instant single-click HEX copying.
  • Live real-time UI component mockup testing.
  • Color blindness accessibility preview.

Limitations

  • Image color extraction uses sRGB pixel sampling approximations.

Client-Side Data Privacy

All image rendering, color matrix calculation, and file exports run strictly in your browser session.

Zero Server Storage

Uploaded images and generated palettes are never saved or sent to external servers.

Tips

  • Ensure your call-to-action button color achieves a WCAG contrast ratio of at least 4.5:1 against the background.

Frequently asked questions

What is WCAG contrast ratio compliance?

WCAG contrast ratio measures the legibility of text against its background. A minimum ratio of 4.5:1 is required for standard text to pass AA standards.

How does the Color Blindness Simulator work?

It applies SVG matrix color transformations to mimic Protanopia, Deuteranopia, and Tritanopia visual conditions in real time.

Can I extract solid color palettes from images?

Yes. Click the Extract from Photo button to upload an image and derive dominant solid color swatches.

What is the 60-30-10 UI design rule?

It is a classic design balance rule: 60% dominant background color, 30% secondary structural color, and 10% accent call-to-action color.

Does this tool export tokens for Figma?

Yes. You can export Figma JSON tokens directly importable into design systems.

Is the Flutter Dart code ready for mobile production?

Yes. It generates a clean AppColors class with static Color constants.

What is the difference between shades and triadic harmonies?

Shades alter lightness levels of a single hue, while triadic harmonies select three evenly spaced colors around the HSL color wheel.

Are uploaded images saved on server storage?

No. Image processing takes place entirely inside your local browser memory.

Can I shuffle generated palette positions?

Yes. Click the Shuffle button to re-order color placements across UI components.

Is this solid color generator completely free?

Yes. All design token exports and accessibility features are 100% free with zero registration.
