Edit Mode is too dark

Is there a way to lighten up the shadows in edit mode? I’ve tried adjusting the OpenGL lights but found it difficult.

You can change the color of editmode faces and transparency under the theme menu.

Thanks. Lots of good stuff in there. I’ll have to get into the habit of going into Themes when I’m having trouble with a dark corner. Bumping up Vertex Size and Color will be good. I think I got what I wanted with the OpenGL Lights by distributing them evenly and blasting the Diffuse Color on full.
