Board Thread:Dragon Story Breeding/@comment-28735997-20181005203105

Bred Tracker(red,black,fairytale) and Fire (red) and got 7 hr timer. Breeding calculator says it's either clown (yuck!) or Seer dragon which are both YELLOW and blue. I know black can split into purple and blue,but where the heck did the yellow come from?! TIA for any logical response.
