It is absolutely not just the type, and it is ALL about the certain dragon. For pearl, the dragon pairs had to be snow and seaweed. You could not do snow and swamp to get pearl. So if the combo for ruby requires an evergreen, (which i doubt), you most certainly would not be able to swap it out for a lichen or reindeer.
