Like many others, I find the DoW III art style a bit too bright, I'm looking for a mod that makes everything look more "grimdark".
As far as I'm aware, its not something current mod toola can possibly do. In another thread somebody pointed out that lighting settings can make it look much more grimdark, showing screenshots from the world builder. It's up to map makers to make grimmer lighting settings, as other than that I don't think it can be done.
Ctrl+win+c turns your monitor in greyscale mode. Your own grimdark.
