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 Emerald?
#50C878. That is 80, 200, 120 in RGB, and hue 140°, saturation 52%, lightness 55% in HSL.
Q. Should text on Emerald be white or black?
Black. Contrast against white is 2.13:1 and against black 9.87:1, so take the higher one if body-size text has to be readable.
Q. What is the complement of Emerald?
#C851A0, 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 60% · M 0% · Y 40% · K 22%. 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 #84858B with protanopia, #7D7490 with deuteranopia and #569B9E with tritanopia. Where those values converge with another colour, add a shape or a label instead of relying on hue.
