vibrant-colors/node-vibrant

node-vibrant is a JavaScript library that extracts prominent colors from images, providing a consistent API across Node.js, browser, and worker environments. It's designed for developers who need to programmatically analyze images and generate color palettes for applications like dynamic theming, image-based design systems, or visual content analysis. The library offers performance optimizations through Web Worker support and maintains consistent results within a user's browser instance, though cross-platform variations may occur due to canvas rendering differences.
