First of all I want to say, this package is awesome. Pretty close to being the highest quality retro shaders for URP. I think features such as color limiting (via a palette or slider) and dithering to go with that would be great additions to the CRT filter.

Those are great suggestions, thanks! I've been working on the CRT filter the last few days actually (thinking of adding a few VHS damage effects), so I'll see if I can work those in. At least, dithering has been on my mind a while.

Hey! Just to let you know - I just pushed an update that includes dithering. I chose to include it in the Retro Lit shader rather than the CRT filter so you have more control over which objects use dithering, and because Retro Lit already supported color bit limiting, but I hope that's close enough to what you needed!
