Understanding color formats
Color values on the web can be expressed in many equivalent notations. HEX encodes each RGB channel as a two-digit hexadecimal number — compact and universally supported. RGB splits the same information into three decimal values (0–255) for Red, Green, and Blue channels.
HSL (Hue, Saturation, Lightness) and HSB/HSV (Hue, Saturation, Brightness/Value) are perceptual models that map more closely to how designers think about color. HSL is native to CSS; HSB is the default in tools like Photoshop and Figma. RGBA and HSLA add an alpha channel for transparency.
HEX → #FF8731 RGB → rgb(255, 135, 49) HSL → hsl(26, 100%, 60%) HSB → hsb(26, 81%, 100%)
