I can weigh in on this one pretty well. My Dragon is actually the offspring of a high yellow bred to a high red dragon. He is mostly a pale yellow, with very little red in him. I actually saw one of his brothers, and he had what looked like a candy cane for a tail. The offspring of the clutch varied a good bit, but if my dragon is any indication of what they mature into, its a little disapointing. When he was a hatching his color was pretty crazy, but with each shed he gets a little less colorful, and is evening out into a nice mustard color. I would be interested to see what his brothers and sisters looked like, and what that dragon with a candy cane tale has matured into. It is a cross that is pretty interesting, but its up to you to decide what you want out of your babies. A pure cross would probably sell better, when it came to marketing your offspring, but a mixed cross is always fun as well! Good luck!
I will get a picture of my dragon time permitting, some time in the next few days for you.
