Change the background color

Hello! 

Im setting up a new DraftSight (locally) and trying to configure a good starting file. The issue is that I can't seem to change the background image from black to more gray (similar to AutoCAD).

I've looked around a bit, and what I've found is that you should type "Modelbackgroundcolor" and then select an RGB code for the desired color. However, when I enter the code I want (40,40,40), it turns orange instead, and despite trying repeatedly, I can't seem to make it work. Now, I've accidentally made the "Command Window" completely white, so I can't see commands (not sure how I managed that). 

Do anybody know how to fix the background color and the command window? 
 

Best Regards
