I believe the Wolfe and Diamond FX have many of the same basic colors, not the new colors that each company is coming out with, but their first colors, because Diamond FX was an offshoot, as far as I know, from Wolfe. I don't know all the details, or how it happened exactly, because I came in later, just to become a seller when Diamond FX came to the states.
Here's a link to my website with demo of the purples with the Diamond FX metallix violet included below. If you can't click on it, just paste this link into your browser.
