background color

Hello everyone
A while back download NVIL and did not try it out to long, but now I am going to make another run at it.
So far i am impressed.

Anyway I prefer to work with a darker background color.
I have search all other the gui and can not seem to find where to change it.
any help would be great.

edit > Preferences > Colors tab

viewport color1 and 2 is what you want.

ok that was easy enough.
I dont know why did not just try that in the first place.

Thanks
