Actually, Divinity was quite dark on my system. There is a darkness and gamma setting in the video options, however, that fixed that.
For beyond Divinity, the first act is suppose to be dark, what with being in a dungeon and all. There are also other areas outdoors, giant mushrooms, etc that should be lighter.

"But anyway, personally, I'd like some lighter graphics as well. *sigh*"

Maybe a shinny, happy meadow with a rainbow, where elves and pixies come out and sing to you (think smurfs who have been watching too much Barney the dinosaur), trying to get you to join in. Even after you start killing them, they apologize for getting in the way of your sword, and keep singing. <img src="/ubbthreads/images/graemlins/badsmile2.gif" alt="" />
