can't see what's what

I'm struggling with the tutorials! So frustrating. Features can't be constructed and I can't tell why. I try to go back and fix them, but the feature closes out and I have to start over. It happens again and it tells me that lines overlap, but I can't see where.

I could go on and on about my frustrations, but here is my question: The edges of my part are black. The sketch entities that I'm drawing are black. Previous sketches are dark blue. Part surfaces are grey. How can you see what's what?
