Please guys, I have big problem to a color set up, although in basic set up is turned on a grey color (as defaut) still I have some orange color as you may see on picture bellow. How can I solve it? Just to notice you that isn't a default setting, I get it after I fixed something what I can't remember and even how I did it.
Do you think this is the result of having selected something and now it can't be deselected? If that's the case (and hitting the Escape key on the keyboard doesn't work) try selecting: "File > Utilities > Part Cleanup" - check "Remove Extraneous Highlighting" and hit OK.
If you means default color of solid body at creation time,
you can set it from [Preference > Object].
Chose Type (solid body) and specify color.
(Most of Preference setting is part specific. And default setting is come form Template part. )
