Just an (on topic) opinion piece:
For me, purely from a personal standpoint, I really have grown to dislike textures that have been forced into the Doom palette.
I don't mean textures designed for it from scratch; I mean textures that did not originally have a palette that was particularly close to the Doom palette in the first place. I, like I'm sure most people here, have seen so many textures like this over the years that I can spot the specific Doom palette artefacts that are caused on certain textures. You know, areas of a once mossy wall, or a slimy metal tank which now have overly large patches of greens from the 152-159 range that have lost much of their detail and subtlety as a result, large areas of grey that obviously look as if they must have had a different colour at one point, brown areas of a texture illogically having pixels from the two main brown ranges in Doom in the same area and sometimes a few dark reds thrown in for good measure. etc. etc. And if a texture had any blues other than strong (R 0 G 0 B lots) ones... Blergh! Honestly, to me it just looks awful.
I'd much rather have textures designed specifically for the Doom palette, or textures done in colours so that they compliment the Doom palette even though they might have some colours outside of it (which can actually be quite effective) or, if a texture doesn't suit being forced into the Doom palette then have it be used in its original colours.
Myself, I gave up really caring about the Doom palette a long time ago. Being freed from it is, IMO, one of the greatest things about GZDoom. I don't mean "well that gives me a license to put as many contradictory styles into a map as possible" (though I guess it kind of does

). Things still need to compliment each other. However, seeing so many once beautiful textures made ugly by brute-forcing them into Doom's colour range is such a shame. They don't look good. /opinion
