Orange dreams are common in the wild similar to yellowbellies, there are 4 proven bloodlines and probobly a dozen other suspected bloodlines/allelics that may or may not prove out, so it wouldn't be that crazy, if you told someone she was a dreambee, most people wouldNt question it. Her sibling looks a bit more yellow than a normal spider, but the female parent has that "shine" to her and I suspect she's a bit more orange in person and after shedding. Either way you have something very cool here and I'm not saying I have a clue what it is, but I'm certain it's genetic.
