The options are stored as arrays: myColor: [255, 0, 0] When the colors are used then it takes a little JavaScript finessing to apply them: ctx.fillStyle = 'rgb(' + myColor.join(',') + ')'; Being able to simply write the following, as would be the case with your idea, would be nice. ctx.fillStyle = myColor; Another example of using arrays for colors, both RGB and HSB can be found in the Mootools JavaScript framework: http://mootools.net/docs/Plugins/Color Note that also like your example the Mootools color plugin does not have separate rgb and rgba methods. It is smart enough to recognize that if there is a fourth value in the array it refers to the alpha. I never quite grasped why there is both an rgb() and rgba() in canvas. It seems like rgb is all that would have been necessary, and if a fourth value is passed it obviously refers to the alpha. - Greg
