Doom Pallete has Redudant Colors?

[Doom Marine]

In the Doom Pallette, I noticed that the color White [R255,G255,B255] showed up at least four times in the Doom Pallette, and the darkest shade of Red [R067,G000,B000] twice.

If say, I were to replace three of those pure whites with some shades of reds, how would it affect the existing graphical resources in Doom?

Those redundant colors could be put to good use, I think.

It seems most of the repetitions were made to make full color scales. Messing with them would cause problems where those colors are used on the existing graphics.

There's also like 5 or 6 shades of really dark gray (R4,G4,B4), but there's nothing you can do about any of it. Messing with the indeces will indeed fuck up the rest of the textures. You would have to modify the palette and then apply that palette with some external program to remap the indeces of each texture to the new colors (using the closest available match). In theory, after reworking the palette, you could have room for yet another full color (say purple or yellow/gold?). Only problem I can see someone running into is conflicts with Doom's color translations (green/brown/rose/dark gray).

I think I'll stick with the Doom Palette in this case; I'd not want to reprocess the rest of the iwad textures and add another 10MB to my pwad.

The problems caused by changing certain redundant colors is confirmed by my testing: I replaced three of the pure whites with dark shades of red, thus some pure white colors including the god-mode's glowing eyes are changed. Potentially useful stuff, but not worth the dredging of my resources and time.

You can see the effect of color changing directly in XWE. When you modify a color in the "PLAYPAL" entry you can see the result in the "COLORMAP" entry.

I've seen several wads (Darkest Hour comes to mind) where the blue shades have been replaced with lighter blue ones to make water and sky textures look more realistic. This method could be repeated for several other colors. I suppose this is the easiest and safest way to change pallete.

BTW: the pallete is only 10 kilobytes, not MB.

m0l0t0v: By changing some redundant colors into completely different ones [as opposed to lightening the shades], it would require the reinsertion of all the graphical lumps that used those redundant colors.

The God-Mode case, once again, is a good example: If I were to change the three of the four pure whites to black, then certain areas in the God-Mode eyes would turn black, giving the Doomguy's God-Mode a snakeye's appearance. Therefore reinsertion of the God-Mode gfx into the PWAD would be necessary to correct the God-Mode's colors, at least to the extent of my knowledge.

I see what you mean.

All I tried to say was you can change some of the colors without much trouble (using the COLORMAP to quikly check for unexpected side effects).

Wild Weasel's weapon-mod "Extreme Measures (?)" (ww-xm.zip) used such a modified pallete. IIRC the blue, red and green were changed into different shades, giving some of the original textures a new look. If done correctly this way of changing palletes can make old textures look more original.

I thought you'd like to know this since your first post suggests you're looking for a way to insert new colors in the Doom pallete.
