Something like:
ColorObject.prototype = {
colorNames : {
aqua : "rgb(0,255,255)",
black : "rgb(0,0,0)",
blue : "rgb(0,0,255)",
fuchsia : "rgb(255,0,255)",
gray : "rgb(128,128,128)",
green : "rgb(0,128,0)",
lime : "rgb(0,255,0)",
maroon : "rgb(128,0,0)",
navy : "rgb(0,0,128)",
olive : "rgb(128,128,0)",
purple : "rgb(128,0,128)",
red : "rgb(255,0,0)",
silver : "rgb(192,192,192)",
teal : "rgb(0,128,128)",
white : "rgb(255,255,255)",
yellow : "rgb(255,255,0)"
},
parseColor : function (acolor) {
var color;
if (/\d*%/.test(acolor)) {
color = Math.round(255 * parseInt(acolor.substr(0, acolor.length
- 1)) / 100);
} else {
color = parseInt(acolor);
}
return color < 0 ? 0 : color > 255 ? 255 : color;
},
red : function () {
return this.colors[0];
},
green : function () {
return this.colors[1];
},
blue : function () {
return this.colors[2];
},
tohexStr : function () {
var output = '#', i = 0; l = this.colors.length;
for (; i < l; i += 1) {
output += this.colors[i].toString(16);
}
return output;
},
torgbStr : function () {
return "rgba(" + this.colors.join(',') + "," + this.alpha + ")";
},
toString : function () {
return this.torgbStr();
},
valueOf : function () {
var l = this.colors.length, i = l - 1, value = 0;
for (; i >= 0; i -= 1) {
value += this.colors[i] << ((l - i - 1) * 8)
}
return value;
},
mult : function (val) {
var i = 0, l = colors.length, output = 'rgba(';
val = val > 1 ? 1 : val < 0 ? 0 : val;
for (; i < l; i += 1) {
output += Math.min(Math.round(this.colors[i] * val), 255) + ',';
}
return output + this.alpha + ")";
}
};
