Right now there's not a display environment that gives easily legible sketches.
Dimensions with the same color as geometry (see Photo Booth makes it very hard to see what’s what.
There’s an Ideastation request to change dimension leader color, which is a good solution, but surprisingly that didn’t get much traction.

Grey Room is much better but it’s too hard to see reference dimensions and underconstrained construction geometry.
Dark Sky is fine in that respect, but the dimensions are the same color as geometry again.
So how about lightening up the reference dimensions and underconstrained construction geometry in Grey Room, and/or making dimensions green in Dark Sky.
