Odie:
Osage orange (Maclura pomifera) will undergo color shift from the bright orange you see following fresh cuts of the wood to a light chocolate brown, with little, if any, hint of orange when the color has finally shifted and is "stable". It becomes a brown wood, eventually. The same is true for mulberry (Morus spp.) which is in the same family (Fig/Mulberry family; Moraceae)- this wood also shifts from a bright yellowish color when freshly cut, to medium brown when the wood's color has finally "matured".
The related species known as Argentine Osage Orange (Maclura tinctoria) is said to retain its orange/yellowish color longer than M. pomifera. I've tried side-by-side tests of woods of both species, and to a limited extent this is true, however even the vibrant yellowish-orange color of M. tinctoria will eventually shift to become more brownish over a year or two, but does retain some "yellow", despite the general color deepening toward brown.
Yes, I think you might have some splainin' to do - You might want to do this AFTER your dentist is done doing any drilling or other potentially painful procedures....😉
