How palettes are made

Our palettes come from two sources. A hand-curated set of designer favorites, and a generation pipeline that builds combinations from classic color-harmony rules (analogous, complementary, triadic, split-complementary, monochromatic and accent schemes) inside the perceptually uniform OKLCH color space, then filters out anything muddy, too similar or low-contrast. Every palette is checked so its colors are distinguishable and its names describe the actual colors.
