HEX, RGB, and HSL Models
RGB describes colors through red, green, and blue light channels (0-255). HEX represents RGB in hexadecimal notation. HSL (Hue, Saturation, Lightness) organizes color perceptually around a 360-degree color wheel, making brightness variations intuitive to tweak.
WCAG Contrast Ratio Rules
The Web Content Accessibility Guidelines (WCAG 2.1) require a minimum contrast ratio of 4.5:1 for normal body text (Level AA) and 3.0:1 for large text and UI components. High-contrast themes aim for 7.0:1 (Level AAA).
