I don´t know any site about the veiled you´ve mentioned but I´ve read somewhere about the strange-coloured veileds (which are supposed to be different morphs) and I think that if you keep on searching in this site you´ll definitely find at least one- a yellow/orange male (I suppose his name was Storm).
Ch. calyptratus calcarifer is a hybrid between Ch. calyptratus and Ch. arabicus. I don't think the subspecies has been officially wiped off the lists yet though even though the indication is that its just a hybrid.
