Used to be a guy named Ben Sweet who made crazy colored G10, not sure if he's still doing it though. He was on Bladeforums for a while and used to sell on Ebay but I don't see him either place anymore.
I am unaware of any sources who handle that color combination regularly. However, most of the suppliers can get just about any color combination you want....but there is a catch. You will likely be told that you have to purchase a minimum quantity. I've been quoted minimums as small as two full sheets, to as many a 5 full sheets, with prices ranging from $225 to $400 per sheet, depending on the desired color combinations. I suppose it a person made a huge run of a given knife/design, it might be worth it, but it was too rich for my blood.
I am also looking for purple G10, I went over to Bladeforums, in the knifemakers supplies for sale forum, and found a guy selling burlap scales. I have sent him an email asking about fiberglass laminates. He goes by Fod on the forum, you may want to check with him, or I can pass along here what he tells me when he replies back to my email. Hope this helps someone looking for crazy colors of laminates.
