color-loader

color-loader

A webpack loader that extracts the color palette for an image

Installation

$ npm install --save-dev color-loader file-loader

This loader depends on file-loader, so be sure to install that too if you don't have it already.

Usage

This loader supports JPEG, PNG, GIF, and SVG files and is designed to be a drop-in replacement for file-loader, in case you're already using that. The loader will output the path to the provided image file, along with information about the colors in the image.

import image, {color, colors} from 'color-loader!./path/to/image.jpg';

• image is the image path generated by the file loader
• color is the most dominant color in the image
• colors is an array of the dominant colors in the image

You can use it in your webpack configuration, too! This means that all images that you import or require will always return the colors extracted from the image.

{
  // ...your awesome webpack config options
  module: {
    rules: [
      {
        test: /\.(jpg|png|gif|svg)$/,
        use: 'color-loader'
      }
    ]
  }
}

Options

You can pass along any options you would normally pass to file-loader.

Example

This image:

Will result in these colors:

• #3a4f25
• #b37a5d
• #78993b
• #839795
• #8c472f

You could use it in a React component like this:

import image, {color} from './example.png';

const Component = () => (
 <div
   style={{
     backgroundColor: color, // #3a4f25
     backgroundImage: image
   }}
 >
   <h1>They ate the Pokémon...</h1>
 </div>
);

And it might look something like this (results may vary):
