Converting color values

Is there any simple way to convert an RGB color to and from other colors (e.g. HSL, Lab)?

I thought I had  a way to have SolidColor do the conversion, but I can't seem to get it to work...

Does putting the solid color in the app's foreground then pulling back the other values not get you what you need? I don't do much of this so I could be a mile off…

var rgbSC = new SolidColor()

rgbSC.rgb.red=0;
rgbSC.rgb.green=204;
rgbSC.rgb.blue=100;

app.foregroundColor = rgbSC;

$.writeln(app.foregroundColor.cmyk.cyan);
$.writeln(app.foregroundColor.cmyk.magenta);
$.writeln(app.foregroundColor.cmyk.yellow);
$.writeln(app.foregroundColor.cmyk.black);

$.writeln(app.foregroundColor.hsb.brightness);
$.writeln(app.foregroundColor.hsb.hue);
$.writeln(app.foregroundColor.hsb.saturation);

You don't need to set the foreground color

var sc = new SolidColor;
sc.rgb.red = 200;
sc.rgb.green = 145;
sc.rgb.blue = 96;
$.writeln('RGB '+sc.rgb.red+':'+sc.rgb.green+':'+sc.rgb.blue);
$.writeln('Lab '+sc.lab.l+':'+sc.lab.a+':'+sc.lab.b);
$.writeln('HSB '+sc.hsb.hue+':'+sc.hsb.saturation+':'+sc.hsb.brightness);
$.writeln('CMYK '+sc.cmyk.cyan+':'+sc.cmyk.yellow+':'+sc.cmyk.magenta+':'+sc.cmyk.black);
