back from vacation for posting march 7th with small tits
Not sure if this function already exists somewhere, but I made a couple custom nodes for comfy since I was annoyed tard wrangling mixes with washed out colors if anyone is interested, just drop the files imto custom_nodes folder if you want to try them
Main useful one applies a luminosity s-curve to images, meant to be run on images right after vae decode (and then sent to hires pass nodes). Should be fine on defaults, just don't raise y3 unless you want to go blind. (or are doing some spot color/monochrome style) Defaults may not have good effect on images with backlighting.

Other one was meant to do monkey color grading by a warm/cool axis but it also applies a multiplier on chroma which is some more snake oil to have fun with, use this node with low strength
