David did you look on eBay because I have seen some there but how true the colors are to what you get if you buy would depend on the honesty of the seller.
Mine are all the pale yellow. I still have as I think I told you before the true orange. If you want a piece of that I will gladly send it to you. It looks like this.
I bought it as the Zygocactus x orange. I was lucky it was a true orange My camera does not show how really orange it is.
