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 #11a and #1111AA the same color?
Yes. CSS doubles each digit of a three-digit hex, so #11a expands to #1111AA. Only 4,096 colors can be written in three digits, and this is one of them.
Q. What text color works on #1111AA?
White text. Contrast against white is 12.47:1 and against black 1.68:1, so pick the larger one — WCAG asks for 4.5:1 at body size.
Q. Which named color is closest to #1111AA?
Navy. It is not an exact match, so where color matters use the hex code itself rather than the name.
