Gentlemen don't notice these things, and if they do, the logical assumption is that something's been replaced. Suppose you bought both jacket and waistcoat at the same time, and the cleaners lost your waistcoat. Would you throw away the PC and start over again? Of course not. You'd buy another waistcoat and get on with life. I'd avoid a patterned or "tone on tone" waistcoat as they tend to look ridiculously "Palm Beach Country Club" when worn with a kilt. The cut of the waistcoat with a PC is of critical importance. It should be low cut, with three, and no more than four, buttons. So, as other have suggested, try and buy them both at the same time-- but if you can't, then buy a standard black PC waistcoat when you can, and don't worry about matching the exact shade of black.
Sage advice there.
