Color wheel code needs refactoring

[sasha42]

As of 8d54452 the code looks quite ugly, and requires serious refactoring. Things like this:

        // assigning onchange event handler
        cp.onchange = function (clr) {
            var confus;
            var red = (hexToRgb(clr).r);
            var calcr = red*16;
            var green = (hexToRgb(clr).g);
            var calcg = green*16;
            var blue = (hexToRgb(clr).b);
            var calcb = blue*16;
            var obj = {0: calcr, 1: calcg, 2: calcb}
            confus = JSON.stringify(obj);
            console.log(confus)
            ws.send(confus);
            colors = clr;
        };
