Hi Cade what is the reason you choosing another colour pickguard ? I would say in most cases they should be pretty damn close in shape, might need a slight modification to fit but most likely it will fit okay.
I wouldn't spend up on genuine Fender pickguards, I would order a couple of cheaper ones on fle-bay so you have 2 to choose from. I usually grab at least 2 colours too to experiment how it looks with the hardware on. Like black or tortise shell red or another colour that may suit the stain/paint colour
