HDR PQ Red color fix LUT for ReShade

In a nutshell, makes reds more red and less orangish in HDR PQ mode, and has optional tone/brightness included.

*Screenshots are rough approximations/edited since HDR can't be properly screenshotted. What the Red looks like is up to you and completely adjustable.

This is my personal LUT file for the ReShade LUT shader to correct the skewed red colors when I enable HDR. I use HDR PQ mode (the other HDR mode doesn't mix with ReShade for me) on a PG27U monitor (1000 nit and I use 1. 60 tone midpoint), so I expect it to look great. This monitor has a Wide Gamut mode for SDR which makes red in particular look fantastic, but for whatever reason the normal gamut mode looks orangey with RGB (255 0 0) red, and the HDR mode doesn't let me use Wide Gamut. (Actual HDR video seems to look great, but I suspect Cyberpunk 2077 does not have an actual HDR color gamut and just carries SDR color into HDR mode; missing out on some of the spectrum.) When enabling HDR, reds got orangish and magenta/purple got bluish. Given that you see the red UI at all times, this was very annoying, so I fixed it. If you have a similar problem, give this mod a try.

This LUT is for HDR PQ mode only. It is not made for SDR.  It pushes the incorrect orangey-reds toward magenta-red so the color looks much closer to how it should. That is what the Chroma (color) slider in the LUT shader settings will adjust.

(Recommend this slider . 500 - 1. 000, refer to your UI color and slide Chroma to any Red you wish!)

Special note: ReShade settings can go past their slider minimum/maximum should you want it to. Click the slider, press Down Arrow, Up Arrow, Enter. Now you can type in a value above 1. 000

The Luma (light) slider acts as a cheap pseudo-tonemap to brighten up your HDR experience while keeping the dark spots dark. It lowers the maximum whitepoint a bit and the midpoint a tiny bit as well. It's fine to leave this at 0 if you don't want extra brightness.

(Recommend this at about . 250 maximum to brighten the day. Adjust it while looking a bright sky/sun to avoid making bright things blend together)

HDR capable Monitor. HDR PQ mode ON in-game.

Installation:

Extract this file to Cyberpunk 2077\bin\x64\reshade-shaders\Textures

Open ReShade in game and turn on LUT.fx

Turn off Performance Mode if it's checked, and find the LUT.fx settings. Type "LutHDR.png" into the fLUT_TextureName box.

Adjust the Chroma and Luma sliders as you see fit. Use the UI red as visual reference for the chroma slider .

The result is subjective depending on you and y
