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 Vermilion?

#E34234. That is 227, 66, 52 in RGB, and hue 5°, saturation 76%, lightness 55% in HSL.

Q. Should text on Vermilion be white or black?

Black. Contrast against white is 4.12:1 and against black 5.1:1, so take the higher one if body-size text has to be readable.

Q. What is the complement of Vermilion?

#35D5E3, 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 71% · Y 77% · K 11%. 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 #9D9C37 with protanopia, #A7B338 with deuteranopia and #DB3A3B with tritanopia. Where those values converge with another colour, add a shape or a label instead of relying on hue.
