Color models are mathematical systems that represent colors as tuples of numbers. Each model is optimized for different applications (screens, printing, human perception).
Additive color model – light is added to create colors. Used in monitors, cameras, and digital devices. Each channel ranges 0–255 (8‑bit) or 0–1. Full combination gives white (255,255,255).
Compact representation of RGB for web: #RRGGBB. Each pair corresponds to decimal 0–255 (00‑FF). Shorthand #RGB expands to #RRGGBB (e.g., #F00 = #FF0000).
Intuitive for humans: Hue (0–360° color wheel), Saturation (0–100% intensity), Lightness (0–100% brightness). Lightness = 50% gives pure hue; 0% black, 100% white. Ideal for creating shades/tints.
Also called HSB (Brightness). Value represents the maximum intensity of the color. Value = 100% gives full brightness, while Saturation reduces toward white. Often used in color pickers because it separates color from brightness.
Subtractive color model used in printing. Colors are subtracted from white light. Conversion from RGB is non‑linear and depends on color profiles.
Designed to be perceptually uniform – a change of the same amount in a value should produce a change of about the same visual importance. Used in color management.
| Model | Lightness / Value | Typical Use |
|---|---|---|
| HSL | Lightness = average of max and min RGB (midpoint between black and white). Pure colors at L=50%. | CSS, design systems, UI palettes |
| HSV | Value = maximum RGB component. Pure colors at V=100%. | Legacy color pickers, computer vision |
Different devices display different ranges of colors (gamut). sRGB is the standard for web, while Adobe RGB and ProPhoto RGB are wider. LAB covers all visible colors.
