This is just a PLAYPAL/COLORMAP replacement that changes DOOM into a *mostly* black and white game. The red range is left as-is.
I originally put this together back in the late nineties and it languished on my hard drive afterwards. Sometime recently, I think it was the film "Sin City" that reminded me of this.
I looked around and there is another B&W PWAD called "ww-nfoir.wad". However it doesn't leave the red range alone: That's made B&W too.
I also threw in some new BSPLAT sprites taken from "gib.wad"; another PWAD sitting on my HD.
