OK! Thank you for your opinion and for the really pretty phrase I have quoted ๐ !
In my task I have to work with lines (edges) on the faces backgrounds. Therefore the relation between the edge screen colors (stable) and the faces screen colors (changeable) is very important to me. So I really see a problem ๐.
Thank you again for your answer. I will take into consideration the SketchUp color visualization properties you have mentioned. Good luck!
