var Impression = require("impression");
var imageData = fs.readFileSync("path/to/image");
var image = new Image();
image.src = imageData;
var imp = Impression(image);
imp.dominantColor.toRGB();
imp.pickedColors.toHexString();
imp.highSatColors.toRGB();
imp.chromaColors.toHexString();
imp.achromaColors.toRGB();
/*get [{r: 255, g: 255, b: 0}, ... ]
