mr.ska said:I've stayed with the default colour, and I've done so regardless of the CAD system I was using. I find white to be too hard on the eyes, and black tends to hide too much shaded detail. The standard default blue seems to be a good compromise.
For what it's worth, if a system has offered a "graded" background colour I've never bothered with it. I found very little benefit from it, if any.
