Hatch properties in AutoCAD 2011now includes Background Colour providing you with more flexibility and control. Applying a Background Colour enables you to create the effect of layered hatches in a single object. For example, you might create a brick Hatch with a Background Colour to represent the bricks and Hatch Colour to represent the mortar in an elevation drawing.
The new Background Colour can be found on both the Hatch Creation and Hatch Editor TAB.
You will also find the Background Colour property in Properties when a Hatch is selected.
