I was about to say the same thing.
great minds think alike...
The colours of the sun.
Yellow through to red.
One color wouldn't suffice. Has to be at least three. To me, the most noble, honest and all that costume is Captain America's. But then again, I'm prejudiced toward anything American.
There's something about red, white and blue that just conjures up images of greatness.
cyan, black, and yellow
Purple represents nobility and white for purity/justice and whatnot
yellow and blue
doesnt get clearer than supermans colours
White or Sliver
