Does anyone know whether its a trivial matter to change the color of 
some pixels of an IconImage? I know I can work with it through a 
BufferedImage but how then do I go about changing the color. I suppose 
it is not as simple as changing an entry of some palette.

It depends on your definition of trivial.

Just a rough untested sketch, if you want to do it the old, slow way:


   import java.awt.image.*;

   class MyFilter extends RGBImageFilter {
	public int filterRGB(int x, int y, int rgb) {
		// do some change to rgb
		return rgb;
	}
   }


   ImageIcon ii = ...;
   FilteredImageSource fis = new FilteredImageSource(
	ii.getImage().getImageSource(),
	new MyFilter());

   Image changedImage = Toolkit.getDefaultToolkit().createImage(fis);

   ii.setImage(changeImage);

   //
   // inform the users of the ImageIcon that they probably need to
   // repaint themself
   //
