How to read this

  • A hex code writes red, green and blue as two hexadecimal digits each. #ff0000 is red at full strength and the others at zero.
  • HSL states hue (0–360°), saturation and lightness. Nudging a colour brighter means changing one number, which is why it is easier to work with by hand.
  • Text contrast follows WCAG. Body-size text needs 4.5:1 or better, and 21:1 between white and black is the maximum possible.
  • The colour-blindness row computes how this colour appears under three types of colour vision deficiency — the reason never to encode information in colour alone.

Frequently asked questions

Q. Are #20c and #2200CC the same color?

Yes. CSS doubles each digit of a three-digit hex, so #20c expands to #2200CC. Only 4,096 colors can be written in three digits, and this is one of them.

Q. What text color works on #2200CC?

White text. Contrast against white is 10.83:1 and against black 1.94:1, so pick the larger one — WCAG asks for 4.5:1 at body size.

Q. Which named color is closest to #2200CC?

Ultramarine. It is not an exact match, so where color matters use the hex code itself rather than the name.
