Color model cheat-sheet
- HEX — 6 or 8 hex digits prefixed with
#. Each pair is a byte for R, G, B (and optional Alpha). CSS-friendly shorthand. - RGB — three 0–255 integers for Red, Green, Blue. Matches screen pixel rendering directly.
- HSL — Hue (0–360° on the color wheel), Saturation (0–100%), Lightness (0–100%). Great for "same hue, a bit darker" tweaks.
- HSV — Hue, Saturation, Value. Similar to HSL but V=100% is the purest form of the hue (not white). Many design tools use HSV pickers.
- CMYK — Cyan, Magenta, Yellow, Key/Black. Subtractive model for print. The conversion here is a simple math approximation; real print matching needs ICC profiles.
