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 Black?
#000000. That is 0, 0, 0 in RGB, and hue 0°, saturation 0%, lightness 0% in HSL.
Q. Should text on Black be white or black?
White. Contrast against white is 21:1 and against black 1:1, so take the higher one if body-size text has to be readable.
Q. Can I send these CMYK values straight to print?
The computed values are C 0% · M 0% · Y 0% · K 100%. 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 #000000 with protanopia, #000000 with deuteranopia and #000000 with tritanopia. Where those values converge with another colour, add a shape or a label instead of relying on hue.
