I received a question on Twitter today asking how to change the AutoCAD 2011 background color of the Layout.

The default color of the paper in a Layout is white, but perhaps you would like it to blue or maybe black.

If you want to change you AutoCAD background colors from the defaults go to Options>Display> then select the Color button.

In the Drawing Window Color dialog you have complete control over the color settings of most everything in AutoCAD. For the Layout paper background select Sheet/Layout > Uniform Background and then set the color you want.
from the default white.

Slightly related: If you want the old AutoCAD classic icons instead of the ribbon, change your Workspace to the AutoCAD Classic Workspace.

You can even get your AutoCAD to look like it did back in AutoCAD R14 and earlier. AutoCAD UI ~ Best of Both Worlds is Flexible with Traditional Menus or New Ribbon +Plus+ AutoCAD UI Retro Mod’ing Fun
