Initial Seed & Color by Id about randomcolor HOT 3 CLOSED

I was able to solve the first one by just doing this, which could perhaps be added as an example on how to seed the color if you don't include something for initialization:

var rcolor = new RColor;
rcolor.hue = .5;

On the second one, what I did was just save my value for each id, so there was no need to request it more than once. However, I was using it for a gradient, so it was important for me to call the same color again, but with a different saturation. So I did add this:

RColor.prototype.getAgain = function(hex,saturation,value) {
    if(typeof saturation !== "number")  saturation = 0.5;
    if(typeof value !== "number")       value = 0.95;
    var rgb = this.hsvToRgb(this.hue,saturation,value);
    if(hex)
        return "#" +  this.padHex(rgb[0].toString(16))
            + this.padHex(rgb[1].toString(16))
            + this.padHex(rgb[2].toString(16));
    else
        return rgb;
};

That allowed me to do this for creating my gradient:

var color1 = rcolor.get(true);
var color2 = rcolor.getAgain(true, 0.4, 0.99);

Thanks Jeff for the feedback, this makes sense to me and I'll look into working it in.

I know it's been a while but wanted to update this since I've recently reworked this library.

I thought about this some more and I think it should be the job of whatever code is leveraging rcolor to take care of saving or associating colors with IDs. The new API should make it easier for folks to override the hue, saturation and value options.

Going to focus on making sure this does one thing and one thing well (generating random colors). Appreciate you sharing your use case though!
