🎨RGB ↔ Hex Colour Converter
RGB (Red, Green, Blue) and hexadecimal (#RRGGBB) are two ways of expressing digital colours. RGB uses three components 0–255. Hex encodes each component as a two-digit base-16 number. HSL (Hue, Saturation, Lightness) is a more perceptually intuitive model used in design tools. All three representations describe the same colour space.
- 1Hex #RRGGBB: each pair is a two-digit hexadecimal number (00–FF = 0–255)
- 2Red component: first 2 hex digits | Green: middle 2 | Blue: last 2
- 3e.g. #FF0000 = rgb(255, 0, 0) = pure red
- 416,777,216 possible colours (256³) in 24-bit colour
- 5HSL: Hue 0–360° (colour wheel), Saturation 0–100%, Lightness 0–100%
