Hello there. You know, I once worked with a guy who was he was color blind. He said he could see some colors, but others were mixed up. Is that the problem you have?
If you create a bitmap with a small palette on it, you could then have a friend tell you which colors are which. You could then type the colors name next to the color. If that 'map' you should be able to still do pixel art... even if what you see is different from what the image really displayed. If you can't see any colors at all, you can stil do b/w pixel art.
