In this episode, we break down why traditional HSL and sRGB color models fall short when building
modern, accessible multi-theme design systems. We explore how the OKLCH color space decouples
perceptual lightness from chroma and hue, eliminating contrast inversion bugs when shifting from light
to OLED dark mode.
