How color contrast checker works
Adjust the visible color, size, shadow, shape, or text inputs.
Toolkit updates the preview and generated CSS or SVG output immediately so you can copy it into your project.
Privacy
Design inputs are processed in your browser, so you can test colors, gradients, and CSS values quickly.
Limitations
- Generated CSS and SVG are starting points and may need design-system adjustments.
- Color accessibility depends on actual text size, background, surrounding UI, and WCAG target level.
- Browser-generated image and icon previews are useful for quick assets but should be reviewed before production use.
FAQs
Can I copy the generated CSS or SVG?
Yes. The tools show copyable output that you can paste into a stylesheet, component, design note, or prototype.
Are generated palettes automatically accessible?
They are designed to be practical starting points, but you should still check contrast for each foreground and background pair.
Does Toolkit upload my colors or images?
Supported color and design tools run in your browser and do not need an account.
Why does the preview differ from my app?
Your app's fonts, rendering, CSS reset, color management, and surrounding layout can change how the same values feel in context.
