Convert, compare and build color scales that survive light and dark mode.
See a palette the way readers with protanopia, deuteranopia, tritanopia or achromatopsia see it, and get told which pairs collapse into each other.
Check a text and background pair against every WCAG 2 threshold at once, with a live sample in both sizes and the ratio as you adjust the colors.
Paste a color in any notation and read it back in all of them, including OKLCH, Lab and Display P3, each one a click from your clipboard.
Blend two colors across as many steps as you need, in OKLCH or sRGB, and copy the ramp as color-mix() declarations or as plain hex.
Build a palette from one color using the classic hue relationships, each hue shown at five lightness steps and exported as @theme variables.
Put the same two colors through both interpolation spaces side by side, see where sRGB loses its chroma, and copy the gradient that keeps it.
