They are yellow not orange. Xanthic = Yellow. I have a pair and they look very different than any of my Tangerines by a long shot. I don't consider them Tangerines, though they may have initially come from Tangerine lines, you'd have to ask the breeders to be sure (I'm not sure if I can say their names).
This is going to be a start to a project that i have gotten some good reviews from a few select people. yes this is 100% from Jeff Galewood. I have a few more that i will be posting pics of. Not Hyper Xanthics but some sweet MS's and such. As well as some BS Het Bells and BSB
