apply shader to world texture

[XFawkes]

There is an option to apply a shader to elements, peds, vehicles etc. I was thinking of applying shader to some effects. There is a well known nitro shader which changes the colour for every player. I know that there should be a way to make 2 same nitro effects in 2 different colors/textures. How could I try to apply shader to only chosen effects - maybe from createEffect? Or I am sure that there should be just a way to do it in fx files - but I am dump in these so I am just asking.

I believe it's possible to do that, just have to know the world texture names.
