Frequently asked questions
How do I pick a color from my screen?
Click the Eye Dropper button. This uses the browser's EyeDropper API (available in Chrome and Edge) to let you sample any pixel from anywhere on your screen — including images, websites, and other applications.
What is the difference between shades, tints, and tones?
Shades are created by mixing black into a color, making it darker. Tints are created by mixing white in, making it lighter and more pastel. Tones are created by adding grey (reducing saturation) to create more muted, earthy versions of a color.
Which color formats are supported?
HEX, RGB, HSL, and CMYK values are shown for every selected color. Click any code box to copy it instantly. These formats are compatible with CSS, Tailwind, Sass, Adobe Photoshop, Illustrator, Figma, and most other design tools.
What are the trending presets?
Curated, ready-made color combinations across categories like UI, Nature, Pastel, Bold, Monochrome, Warm and Cool tones. Search or filter by category, then click any swatch to load it straight into the picker.
How is contrast ratio calculated for WCAG accessibility?
Contrast is calculated using the WCAG 2.1 relative luminance formula, comparing the lightest and darkest pixels. A ratio of 4.5:1 or higher passes AA level for normal text, while 3:1 is required for large text. Achieving a 7:1 ratio satisfies strict AAA compliance. This tool instantly evaluates contrast against both white and black backdrops to guarantee your user interface meets modern global digital accessibility standards.
Can I use the color wheel to fix WCAG accessibility contrast issues?
Yes. You can drag the interactive color wheel and adjust the lightness slider in real-time while watching the live Accessibility badges. This allows you to instantly tweak non-compliant contrast ratios until they meet strict WCAG AA or AAA web standards directly inside your browser.
Can I export a shade or tint scale for use in code?
Yes. Click "Export Scale" next to the Shades, Tints or Tones tabs to download the current 10-step scale as a ready-to-use CSS file with custom property variables.
The Secret Formula for Color "Dual-Pass" Colors
To make a color pass WCAG contrast guidelines (≥ 4.5:1) on both white backgrounds and black backgrounds simultaneously, it has to live in a specific relative luminance sweet spot.
How to pick accessible values on the fly:
When creating your own color selections, look closely at the HSL values displayed on your master picker card:
- Keep the Lightness (L) value strictly between 35% and 55%.
- ⚠️ If a color is too bright (L > 60%), it will automatically fail readability scores on white backgrounds.
- ⚠️ If a color is too dark (L < 30%), it will fade out and fail readability scores on dark backgrounds.
