The Magic of Accessibility in Color Perception
summary
Shows that converting colors into a perceived-luminance space (OKLCH) fixes contrast mismatches across hues. Uses Evil Martians’ generator to build coherent color scales, checks them against WCAG, and reports reproducible contrast numbers (e.g., 5.9 for 800/200 and 2.9 for 500/100) yielding a readable palette that scales from yellow→green→blue without per-pair manual adjustments.
