Part Color Display in eDrawings

I am using Solidworks 2012 SP2 64bit and when I save my assembly to eDrawings it does not maintain the colors I have for my parts.

I always select a material type for my parts then go to the Display Manager tab on the browser, right clitk on the Appearance created for that material and select Edit Apearence then I change the color. I do not change the colors in the assembly I always do it in the part file.

I am consistent on how I do this but when my assemblies are saved to eDrawings format it will display some parts in the color I set but most show up in the standard color for the material which is usually a shade of grey for steel parts.

Any ideals on what I am doing wrong or why some parts keep their color and some do not?
