Here is my final offer: the blue is the Skylight color, the background is the complementary color - an orangish hue.
The smaller icons are much more difficult to adjust - each pixel has to be perfect and they need to get lighter to show up.
The important sizes are 48x48, 32x32 and 16x16 as far as Windows usage goes - I use these to customize folder icons.
