OKLCH is a newer CSS color space that's perceptually uniform: equal numerical changes in lightness, chroma, or hue feel like equal visual changes. HEX is sRGB-based and not perceptually uniform.
HEX → sRGB → linear RGB → Oklab (via 3×3 matrix) → OKLCH (Oklab in polar form). The result is L (0–100%), C (chroma), H (hue 0–360°).
Use OKLCH when designing modern color systems — accessible palettes, smooth gradients, and dark-mode pairs all benefit from a perceptually uniform space.
