CHROMA_LAB // FULL_SPECIFICATION

WCAG AAA Compliance The "Gold Standard" of accessibility. To pass **AAA**, the contrast ratio between text and background must be at least **7.0:1**. This ensures readability for users with 20/80 visual acuity.

HEX vs RGB **RGB** defines colors by the intensity of Red, Green, and Blue (0-255). **HEX** is simply a base-16 representation of those same numbers (e.g., 255 = FF).

HSL Logic Unlike RGB, **HSL** maps closer to human perception. **Hue** is the type of color (0-360°), **Saturation** is the "vibrancy," and **Lightness** is the amount of white or black mixed in.

Relative Luminance Contrast isn't just about brightness; it's about physics. We use a formula that weighs Green the heaviest (71%) because the human eye is most sensitive to it, followed by Red (21%) and Blue (7%).
