What are OKLCH colors?

OKLCH is a perceptually uniform color model that makes working with colors more intuitive than traditional RGB or HSL. It uses three values: Lightness, Chroma, and Hue, allowing developers to create consistent color palettes by changing only one parameter. Unlike other color models, OKLCH maintains visual consistency across different shades and produces cleaner gradients without muddy midpoints. It can access wider color gamuts like Display-P3 and is well-supported in modern browsers, with fallback strategies available for older ones.
