Color.js is a JavaScript library for color conversion, manipulation, and color science, created by editors of the CSS Color specifications. It supports a wide range of color spaces (sRGB, Display P3, Lab/LCh, OKLab/OKLCh, REC.2020, and more) with proper gamut mapping, DeltaE color difference methods, chromatic adaptation, interpolation, and contrast calculations.

Use cases

• convert colors between color spaces like srgb, p3, oklch, and lab
• generate color palettes by interpolating between colors
• check WCAG and APCA contrast ratios for accessibility
• compute perceptual color difference with DeltaE 2000
• map out-of-gamut colors to a smaller gamut like sRGB
• parse and output CSS Color 4 color strings
• manipulate color lightness, chroma, and hue programmatically

When to choose

• you need accurate, standards-based color science rather than naive RGB math
• you work with wide-gamut color spaces like Display P3 or REC.2020
• you need CSS Color 4/5 compatible color parsing and output regardless of browser support
• you want a dependency-free, tree-shakeable library usable in browser or Node

When to avoid

• you only need simple hex/rgb string parsing and tweaking with minimal bundle size
• you need image-level pixel processing rather than individual color values
• you require a tiny zero-config utility and don't care about color space correctness
