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.
