The same color, five ways

Search a color name or code — or type into any field below.

What do these mean?
HEX — how browsers and CSS store color, base-16 shorthand for RGB.
RGB — how screens make color, by mixing red, green and blue light.
HSL — Hue, Saturation, Lightness. Built for humans: easy to make a color "lighter" or "more muted."
HSV — Hue, Saturation, Value. What most color pickers use — Value is closer to "how bright is the light source."
CMYK — Cyan, Magenta, Yellow, Key (black). How printers mix ink instead of light.

Shades

From white (100%) to black (0%) — tap any row to copy its hex.
