Color Space Conversion Formulas
- HEX to RGB: Break 6-character hex into pairs: $R = \text{hex}(0..1)$, $G = \text{hex}(2..3)$, $B = \text{hex}(4..5)$.
- RGB to CMYK: $K = 1 - \max(R', G', B')$, $C = (1 - R' - K) / (1 - K)$, $M = (1 - G' - K) / (1 - K)$, $Y = (1 - B' - K) / (1 - K)$.
- WCAG Relative Luminance: $L = 0.2126R + 0.7152G + 0.0722B$ (with sRGB gamma expansion). Contrast $= (L_1 + 0.05) / (L_2 + 0.05)$.
