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 Fern green?
#4F7942. That is 79, 121, 66 in RGB, and hue 106°, saturation 29%, lightness 37% in HSL.
Q. Should text on Fern green be white or black?
White. Contrast against white is 5.07:1 and against black 4.15:1, so take the higher one if body-size text has to be readable.
Q. What is the complement of Fern green?
#6D437A, 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 35% · M 0% · Y 45% · K 53%. 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 #61624F with protanopia, #5F5C53 with deuteranopia and #515A5C with tritanopia. Where those values converge with another colour, add a shape or a label instead of relying on hue.
