How to use the color library

Each family page opens with a set of representative colors — a light, a mid and a dark tone from the family — followed by a longer list of associated colors and their hex, RGB and HSL values. Every value is clickable for one-click copy.

  1. Pick a family
    Start with the message you want to send. Blues and greens feel calm; reds and oranges feel urgent; yellows and pinks feel playful.
  2. Choose a lightness
    Within a family, pick a light, mid or dark variant. Light variants work for surfaces and backgrounds; dark variants work for text and borders.
  3. Check contrast
    Use the contrast checker to make sure any foreground/background pairing you choose passes WCAG AA.
  4. Generate variants
    Turn any base color into a full 50–950 scale with the shades generator, ready for design tokens and CSS variables.

Frequently asked questions

How many colors are in the library?

Twelve families plus the 148 CSS named colors plus a curated set of semantic collections. Family pages show representative colors with their hex, RGB and HSL values — a starting point you can extend with the tools.

Can I search for a specific hex code?

Yes. Use the site-wide search (⌘K) to look up any color name or hex value. If you have a specific hex and want to know its family, paste it into the picker or converter.

Are these colors free to use?

Yes. Colors themselves are not copyrightable. Every hex value on this site can be used in any project, commercial or personal, without attribution.

Do you have a full list of CSS named colors?

Yes — see the Named CSS Colors page. It lists every color defined in CSS Color Module Level 4 with its hex and RGB values.
