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.
