Editing Doomguy's Colors Like In A Port

Is there an easy way like in most Doom ports to edit Doomguy's suit color in a sprite with xWe instead of doing it pixel by pixel manually? If not are there any programs that would do that?

Many free image editing programs like The GIMP (cross-platform) and paint.NET (windows only) allow recoloring.

Keep in mind that any parts you recolor to anything outside the green range will then not be modifiable by the engine, which simply swaps any green pixels for pixels of another hue.

Yeah, that won't be a problem. I'm using the sprites for sort of an art project. Thanks for the help though guys.

A program that I've found useful for such tasks is RecolorBMP, which allows you to recolor many sprite images at once.

Thanks for the link myk, I've been in need of something like that for ages :). (Previously, I was modifying the palette and importing it for each individual frame... rather time consuming, to say the least.)
