Quakespasm's water texture settings?

So, since playing Vitaquake I realized the water textures in Quakespasm (the latest version) are pretty muddy looking, very very very brown, and not the easiest to see through when swimming underwater. I’d like to get them to display a green shade like I see when using Vitaquake. Thanks for reading.

You can use gl_cshiftpercent (default 100) to change the opacity of the colour overlay when underwater (as well as for powerups.) I don’t think you can change the colour itself. I’m not sure if this is relevant, but you can also set r_wateralpha (default 1, minimum 0) to change the opacity of the texture itself.
