Importing Colors in Drawing Mode
You can import colors in drawing, part, and assembly modes.
You can use the iges_in_dwg_color configuration option to set the color number of all entities with user-defined colors in an IGES file to point to the corresponding color definition entity. If you set this option to no (the default), the color definition entities in the IGES file are ignored when you import the drawing. Every entity referencing these colors are set to use the color assigned in the color definition entity. If you set this option to yes, the color definition entities in the IGES file are imported to the drawing as user-defined colors, and all entities are set to use them.
