How to make the Front Cup Holders Noticeable!

The "outside" portion of each of the cup holders was painted orange. Now a open cup holder is noticeable when entering the vehicle, but the orange warning paint is not visible when seated inside the vehicle.

Each cup holder was opened, taped, and painted by hand with Testors #? orange paint.

(note that the "track" on the right cup holder should not have been painted)
