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 Cardinal?

#C41E3A. That is 196, 30, 58 in RGB, and hue 350°, saturation 73%, lightness 44% in HSL.

Q. Should text on Cardinal be white or black?

White. Contrast against white is 5.84:1 and against black 3.59:1, so take the higher one if body-size text has to be readable.

Q. What is the complement of Cardinal?

#1EC2A7, 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 85% · Y 70% · K 23%. 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 #7C7B33 with protanopia, #869232 with deuteranopia and #BC2E2D with tritanopia. Where those values converge with another colour, add a shape or a label instead of relying on hue.
