Workspace/interface turned white, it will not change back to grey in preferences interface panel.

[wroblinski]

In Illustrator (most recent up to date version), I did a shortcut and accidentally turned my workspace to white.  I went to preferences ->user interface ->brightness and changed the color.  It changes the interface except for the workspace color, it remains white. However; if I open a new document it does change to the appropriate color.  I just don't want to copy and paste all my work to a new document.  This happened at work on a PC. When I brought the file home I opened it on a IMAC with the same issue.

Try the toggle for Overview Preview which is Cmd-Opt-Shift-Y. Here are two views one with it on and one with it off.

I tried all preview modes with no success, stays white.  I think I'll just copy work into new document.   Really strange.

Thank you! Turning off the overprint preview worked for me. 

[phrosneras]

same happened to me just now. it is not the user interface setting, because that is still set to grey. i dont understand this!? would love to know the reason.

I tried Command+Shift+H and worked for me. Try it out.

It works! Thank you.

I just had this problem and I was able to solve it by toggling hide artboards with command + shift + H.

You saved me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[hh33]

thnx! but why is that? is there a way to change it mannually or is it a programming error?

[Chancery277995691p9r]

No. It is not a programming error. Maybe you mistakenly hide the artboard by pressing the same command Ctrl+shift+H. You can do it manually by going to View menu and Show Artboard

And on a Mac it's Command + Shift +H. THANK YOU!
