How to use

Get the dominant color from an image

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

getColor(sourceImage[, quality])
returns {r: num, g: num, b: 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], ... ]

npm install
