I'm making an "index alpha" sprite. These sprites use the order of the palette for transparency.
Does anyone know of a program that can change the colours of multiple palette entries at once? I can use Paint Shop Pro to edit the palette but there's a LOT of white to change into black. Also something that can transform the palette - ie. change the order in which the palette colours appear - would be useful.
In PSP you can display the palette in order of luminance, but that doesn't actually change the palette at all
