Way to retexture weather?

[Metrovania]

Well it's pretty much what the title says? Is their a way to retexture the screen effects, in particular the weather? More specifically, I'm trying to make the Wisps effect Blue and more Vibrant.

The weather effects don't use simple textures. They're particle effects. Using some simple Lua code you can use your own effects by creating a particle system and attaching it to the camera. You can copy the .ini files used for the built in weather effects from data>scripts>particles. The wisp effects would be p_wisp.ini.
