63 Valiant Signet convertible

New to me 63 Signet, my first convertible! A little rough but solid. Original 3-on-the-tree car, I've got a nice 318 and discs to make this a nice driving car.

Wondering what the original colors were. It seems to be black, but the floor pan is all painted red. Maybe 3BP meant two-tone black and red? Was there a two-tone option for Valiant in 63? Would they really paint the door frames red on an otherwise all-black car?
