You missed what I was getting at, so I’ll try to explain differently, DON’T use the Basic Piece image for anything except for the Ship name. Move the ship images onto their own layer (all of them) - now you can control the background color layer and have it listed above the Ship Image layer in the trait tree thus making it appear to be behind your ship image. Allow the background color layer to be controlled by a dynamic property which changes on the fly based on who owns/places the ship (it will need to be set to a default color at first but thats ok - it will change as required when you pull it from the piece palette - how we handle that is a different story). This will fulfill your criteria in only needing one piece handling the bg color as opposed to duplicate pieces with different bg colors
