Vanilla Colorful Color Picker

vanilla-colorful is a lightweight, framework-agnostic color picker library implemented as W3C standards-based Custom Elements. It serves as a vanilla JavaScript port of the popular `react-colorful` library, offering the same core functionality in a dependency-free, highly optimized package. The current stable version is 0.7.2, released in November 2022, and while no explicit release cadence is stated, it appears to be actively maintained. Key differentiators include its extremely small bundle size (just 2.7 KB minified and gzipped), 100% test coverage, full TypeScript typings, and comprehensive accessibility (WAI-ARIA) and mobile support. It provides various color picker types (HEX, RGB, HSL, HSV) directly usable as HTML custom elements, making integration into any web application or framework straightforward.
