You may have noticed that the default AutoCAD background is an off-white shade. In a comment, Tim asked if this is the same as the Block Editor background. No, not quite. This image shows the different backgrounds and some linework, with black as a comparison:
Paper space is pure white (Red, Green, Blue is 255,255,255), Model space is very pale cream (254,252,240) and the Block Editor is a slightly darker cream (255,252,229). In common with most people in my experience (and most people who need to use drawings with yellow linework), my backgrounds are all going to be 0,0,0 (black). I don’t want to make a big fuss about this, because it’s very easy to change, but I find it kind of funny how this has flip-flopped over the years. There’s a poll about this to the right if you haven’t already seen it.
Whilst light coloured drawing backgrounds are ok for a WYSIWYG, looking at white background all day is tiring, especially so with large flat monitors. Dark backgrounds are much easier on the eye. The legacy of working on black makes the use of yellow common place which when viewed in paperspace (left at its normal white background)makes for problems readinf a drawing – so much so that a lot of guys in this office now have black as a background in PS. Having the ability to flip the colours from the lighter palette to darker set as does white/black would be a usful improvement
on acad 2007 i used to make a WYSIWYG background with colour 196/196/186 and it worked very well when i turned on display plot styles in the options dialog box
the problem is that its hard on the eyes
