Persoanlly, I would go for all purple frame & fork. To me, purple with some silver and chrome components goes together well but a purple frame/chrome fork seems mismatched (unless, of course, there are hints of chrome on the frame itself).

It's kinda like if I were to put a chrome fork on my bike, it would most likely be very out of place even though I have some silver/chrome parts.

You build awesome bikes, man. Can't wait to see pics.
