Getting Started

npm install --save colorthief

If you see an error during install, it is probably related to the system dependencies required by the 'node-canvas' dependency. Follow the steps posted on their repo: https://github.com/Automattic/node-canvas/tree/v1.x#installation

How to use

Get the dominant color from an image

var colorThief = new ColorThief();
colorThief.getColor(sourceImage);

getColor(sourceImage[, quality])
returns [num, num, num]

Build a color palette from an image

In this example, we build an 8 color palette.

var colorThief = new ColorThief();
colorThief.getPalette(sourceImage, 8);

getPalette(sourceImage[, colorCount, quality])
returns [ [num, num, num], [num, num, num], ... ]
