I have an assembly I'm making drawings out of.  The assembly has multiple parts with multiple colors (picture 1).

When I try to open a drawing of the assembly it makes the entire assembly within the drawing one color (picture 2).

Then when I go back to the actual assembly (not the drawing) the assembly is changed to the same color as the drawing (picture 3).  If I rebuild the assembly it fixes the color there but nothing fixes it in the drawing.  Please help!!
