Understanding color models
HEX (#RRGGBB) is the most common web format. RGB specifies red, green, and blue channels (0–255). HSL uses hue (0–360°), saturation (%), and lightness (%) which is often more intuitive. OKLCH is a perceptually-uniform model used in modern CSS — lightness (0–1), chroma, and hue angle.
WCAG contrast ratio compares relative luminance of two colors. A ratio ≥ 4.5:1 meets AA for normal text, ≥ 3:1 for large text, ≥ 7:1 for AAA.
