Zulu, I don't use Home Depot for my paints. Try a local paint store that caters to the professionals. They usually have the fs charts or they will computer match a sample that you bring in. I know that the paints that the plastic modellers use are identified with fs numbers. You can paint a white 3 by 5 card with the one you want and get it scanned in. The stores that are set up for the homeowners don't have the capabilty to do much with fs numbers. Dan.
