  • Checking whether text color meets WCAG AA or AAA contrast against a background
  • Building a smooth multi-stop gradient without hand-writing CSS
  • Generating realistic box-shadow CSS for cards and modals
  • Picking accessible text/background combinations for a design system

Frequently asked questions

Yes — every color tool includes a one-click copy button for the generated CSS. Output uses modern syntax (hsl() with space separators, rgb() with alpha) that works in all current browsers.
It reports against WCAG 2.1 AA and AAA thresholds for both normal (4.5:1 / 7:1) and large text (3:1 / 4.5:1). You see a pass/fail badge for each level so you know exactly where your colors stand.
Yes. You can build linear, radial, and conic gradients with as many color stops as you need. The output CSS includes vendor-prefixed fallbacks where necessary.
For standard sRGB colors they represent exactly the same thing — HEX is just a shorter notation. RGB becomes necessary when you need alpha transparency (rgba) or when working with CSS custom properties that prefer comma-separated values.
The color picker supports sampling from uploaded images using a canvas-based eyedropper. Nothing is uploaded — the image is read locally and discarded when you close the tab.
Modern output (CSS custom properties, conic-gradient, wide-gamut colors) is tuned for browsers from the last 3-4 years. For IE11 support, stick to HEX/RGB values and linear gradients, and test thoroughly.
