I'm looking for a way to enhance display colors just by turning on a shader, without requiring the use of a slider. The reason is that I'm trying to find something that works with Reshadeck on the Steam Deck, a plugin that (currently) only allows one effect to be active at a time and has no way to finetune any settings on the fly.
github.com/safijari/Reshadeck
For example, just enabling Vibrance.fx I can see a difference on my PC, but nothing happens when using the Reshadeck plugin, likely because the settings are not stored into a ReShadePreset.ini file using this method. Does anyone know of a color shader that I could just edit in a text editor? Ideally, I'd have two or three copies of the shader, with different preset values.
