I've recently discovered that Image Alchemy thinks the color channels in a
Sun rasterfile come in the order blue, green, red.  Every other piece of
image software I have thinks it is red, green, blue.  But I don't have any
Sun software nor Sun-original rasterfiles to check this out on.  Can
anybody state *definitively* which is right?  Is the order in colormap
entries perchance different from the order in 24-bit pixels?
