For now, that would be a good solution. Of course, Steve would need to split
the pieces first.

I finally just released it as 104.dat in color 16. A compromise of sorts. The
problem is, other pieces will (do) have the same problem. The fact is, many
pieces having 3xxxx or 7xxxx part numbers refer to that piece as a certain
color. Unlike the typical 4-digit numbers molded on pieces that refer to the
piece no matter what the color.

Not sure I follow. Generally, LDraw parts have used molded part numbers.
Unknown numbers get a 3-digit or less temporary number.
If the part number is found, the temporary number is updated.
But many part numbers that have been found refer to the part in a specific
color - so to use that number, the piece _should_ be colored appropriately.
That would be following James Jessiman's vision of LDraw as a parts database.
But that would mean having some pieces hard-coded in their specific colors.
Something that many people object to. They want the ability to color a piece
as they see fit - whether it exists or not.
Perhaps a compromise and have pieces hard-coded under their actual number, and
a copy in #16 with a 3-digit number?
But many people object to the duplication of pieces and file bloat that would
cause.

All hard questions. As pointed out to me, this program originally started out
as a way to document parts. Accuracy was important to James. And to carry on
his vision of the program would require us to add pieces numbered and colored
accurately.
