W3C keyword reference

CSS named colors, without duplicate swatches

Find any standardized opaque CSS color keyword, copy its exact value, and see which spellings resolve to the same sRGB color. The complete reference keeps aliases together instead of creating duplicate pages.

  • 148opaque keyword spellings
  • 139distinct sRGB colors
  • 9exact-value alias pairs

Source and method

A standard table, not invented color names.

CSS Color Module Level 4 defines each opaque named color as an exact sRGB value. Hexees preserves those keyword spellings, groups exact aliases, and calculates RGB and contrast from the cited HEX value.

Canonical aliases

Nine pairs, one value each.

These spellings are separate valid CSS keywords, but each pair resolves to the same exact sRGB channels. Hexees keeps one canonical swatch and exposes both spellings.

Outside the opaque table

Two useful keywords are not swatches.

transparent

transparent represents fully transparent black. Its visible result depends on the background underneath, so it is not one of the 148 opaque named colors.

currentcolor

currentcolor resolves from the element's color property. It depends on context rather than a fixed sRGB triplet, so it cannot be listed as a canonical swatch.

Accessibility limits

Test the actual pair and the complete interface.

The card ratios compare each exact opaque sRGB value with black and white. WCAG 2.2 AA requires at least 4.5:1 for normal text and 3:1 for large text, but a numeric pass covers only the tested pair.

Gradients, images, opacity, font size and weight, states, focus indicators, and neighboring colors require their own checks. These calculations are not a blanket conformance claim.

Do not rely on color alone to communicate an error, status, selection, or required action; pair it with text, shape, or another programmatically available cue.
