Welcome to the ZDoom Forums!

Looks like forum member Pixel Eater did this for GZDoom: viewtopic.php?f=124&t=58156 & viewtopic.php?f=103&t=58762

Could you use of a blend mode function to combine truecolor luminosity and PE hue and saturation?

Ah ok that's fair enough

It won't be the same because Build's palettes have this strong red bias.

GZDoom has tonemaps, perhaps that tech could be used for 'true colour palette emulation'?

It will come back - when I find some time for it. It only got deactivated because the shader was swapped out with GZDoom's and that one currently cannot do it.

I surveyed the Raze Discord about reasons people like and dislike palette emulation. The most stated reason against it was that it the reduces fidelity. The most stated reason for it was that it improved the color appearance.
All of this this mirrors my feelings about it.

I posted a concept a while back, using ReShade: viewtopic.php?f=347&t=67663 The drawback is that adds color adjustments on top of everything. As a consequence underwater areas, and power ups don't render correctly. If a similar function was inside of Raze, that would in theory bring the best of both worlds.
