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. What is the hex code for Rust?
#B7410E. That is 183, 65, 14 in RGB, and hue 18°, saturation 86%, lightness 39% in HSL.
Q. Should text on Rust be white or black?
White. Contrast against white is 5.56:1 and against black 3.78:1, so take the higher one if body-size text has to be readable.
Q. What is the complement of Rust?
#0E86B9, sitting 180° across the colour wheel. Side by side the two push against each other hardest, which makes it a good accent but tiring over large areas.
Q. Can I send these CMYK values straight to print?
The computed values are C 0% · M 64% · Y 92% · K 28%. Real printing depends on paper and ink, so check against the printer's swatch book when the colour matters.
Q. Is this colour distinguishable with colour blindness?
It appears as #84831A with protanopia, #8B941D with deuteranopia and #B12426 with tritanopia. Where those values converge with another colour, add a shape or a label instead of relying on hue.
