I am guessing this is why you pay them to get it right. I do not have first hand experience with this topic, but I have been on the consumer end of it for custom cases in a variety of colors. The person who was having custom plastic stuff made also told me something to the effect of the company would use the new color on the dirty molds when switching colors, and they would sometimes get cool looking results before getting the new clean color. I was looking for some brown buttons, and was told that there might be some available as a result of this process. Or they could all be made transparent and painted on the inside. The result here is you can have any color, or combination, you want and nothing needs to be changed with the cases. ED can have just the standard color painted on most, and keep some unpainted for those of us who want something transparent or custom. The added benefit is the durability of the paint is massively improved over the current Pandora cases. If this were done I already have some ideas, and know a few people who would probably be willing to do some crazy custom painting for those who are interested. Sounds good to me.
