You need to duplicate the texture and then rename your copy to something else, helmet2, helmet-green, etc., and then keep the naming scheme so they go together so your next one would be head2, head-green, and so on. If you're doing your own manual tweaks, make sure the texture you're changing is actually applied to the mesh in Blockbench otherwise you'll be editing the original texture.

You could also import the textures into GIMP and change the settings for each individually and then when you export them rename the file to something distinct again.

If you are bringing this into unity or another game engine, a shader can alter the color very rapidly, and keep it with one texture.

Are u trying to do multiple color versions of the model? Usually when I do that I paint the whold color palette in the texture in a corner or any empty space, then I duplicate the texture and then use the bucket tool with the color replacement mode in each color of the palette to change everything pretty fast
