A jQuery plugin that extracts the dominant color from images and applies it as the background color of their parent element. It is built on top of rgbaster.js, a small JavaScript library for extracting dominant colors from images.
Use cases
- extract dominant color from an image in the browser
- apply adaptive background color to a card or container based on its image
- dynamically theme page sections to match image colors
- normalize text color for readability over extracted backgrounds
- get dominant colors from a CSS background image element
When to choose
- you use jQuery and want a one-line setup for image-derived background colors
- you need simple client-side dominant color extraction without heavy dependencies
- you want automatic text color normalization over dynamic backgrounds
When to avoid
- you need a maintained, actively updated solution (last release was 2017)
- your project does not use jQuery
- you need advanced color quantization or palette extraction beyond dominant colors
- you need server-side or Node.js image color analysis
