Sky/weather color not working very well with mods (Feature request)

[ZedAmadeus]

Really love the shader, and I'd like to be able to use it with this mod Primal Winter, but since, in that mod, it's always snowing, the shader thinks that it's raining. That turns the fog, sky, and snow particles, which are normally white and cold to a dark grey. Would it be possible to add options to change certain hardcoded colours, like the colour of the sky both when it's raining and not, and also "raindrops?" I tried poking around in the shader code itself but uhh, it's very complicated stuff! So, totally understand if you don't wanna do this, I imagine it might be pretty tricky, and you can't entertain every weird edge case like this, but I sincerely hope it happens. (also I'm on 1.16.5.)
