Hello again! I downloaded IrfanView and it worked wonderfully to apply the palette of the backgrounds. But I found an ¿error? ¿A failure of mine? when using the backgrounds in the game. In fact, they changed color depending on the page on which it was. But they looked rare (reference in the images below). Then, with Photoshop, I applied an additional palette, the Basescape one. It worked, it looks good, but it does not change color. It is not so annoying (in my opinion), but I do not know what went wrong.
What I did in IrfanView was to get the palette of an image of the 40k mod, save it and apply it to my own images. I repeated the same with Photoshop (before applying the Basescape palette) and got similar results.
Any ideas?
I greatly appreciate your kind support.
