Hi, i'm trying to make an function that "mirror" a color;
(example, if user give)

I make this, but with some debug and visual verification, i verifyed that this is not best approach...

1. private static Color mirrorColors(Color bkg, int whichWay) {
2.         // TODO Auto-generated method stub
3.         int rR = bkg.getRed();
4.         int gG = bkg.getGreen();
5.         int bB = bkg.getBlue();
6.         int r, g, b;
7.         switch (whichWay) {
8.         case colors.MIRROR_SIMPLE:
9.             r = rR>=127?rR-127:rR+127;
10.             g = gG>=127?gG-127:gG+127;
11.             b = bB>=127?bB-127:bB+127;
12.             return new Color(r,g,b);
13.         case colors.MIRROR_EXP:
14.             r = (int) (rR>=127?rR-Math.pow(rR, 0.5):rR+Math.pow(rR, 0.5));
15.             g = (int) (gG>=127?rR-Math.pow(gG, 0.5):gG+Math.pow(gG, 0.5));
16.             b = (int) (bB>=127?rR-Math.pow(bB, 0.5):bB+Math.pow(bB, 0.5));
17.             return new Color(r,g,b);
18.         default:
19.             r = rR>=127?rR-127:rR+127;
20.             g = gG>=127?gG-127:gG+127;
21.             b = bB>=127?bB-127:bB+127;
22.             return new Color(r,g,b);
23.         }   
24.     }

Anyone can suggest other ways to mirroring a reference Color?

Thanks
