I don't think many people would get upset about a black Bantam, particularly being a factory colour that year (the other options being red and green if i remember correctly)
However, if you painted a Gold Star blue as I did a few years ago, I'd tell you to be prepared to defend your decision, hahaha. *I'm telling you, it's factory!* Im sure the bloke i sold that goldy to had it silver before he loaded it into his ute!
