I live in a southeast facing apartment and the rooms get plenty of direct sun in the summer.

I have dark wood blinds and wonder if painting one side white would make a big difference in heat inside the rooms during the summer?

There is significant cooling in the room when the sun is out and the blinds closed (vs open). I also have AC if needed. But I've noticed the blinds are warm to the touch themselves.
