When you use the Dragonvale Sandbox and Combo Finder to try to find out pairs for breeding a specific dragon, what is the difference between the blue and gray options? Do gray pairs only work with the Co-op Cave or something? This doesn't seem to be the case because I've definitely bred something in my own Cave/Island using a pair that is grayed out (Iron Blossom, Blazing Gale, etc.), so I can't tell. I can't find this info anywhere!
