MooColor

MooColor is a modern TypeScript library designed for comprehensive color parsing, conversion, and manipulation. Currently stable at version 2.0.0, the package maintains an active release cadence with minor updates and patches, and announces significant breaking changes with major versions. Key differentiators include its strictly immutable API, where all manipulation methods return new instances rather than mutating the original, and robust WCAG 2.1 compliance for accurate luminance and contrast ratio calculations. It provides dual ESM, CJS, and IIFE bundles, making it versatile across Node.js environments (requiring Node.js >=18 since v2) and browsers. The library is fully typed, including Template Literal Types for advanced color string representation, and supports a wide array of color models like hex, RGB, HSL, HWB, HSV, and CMYK, alongside named colors.
