I chose mine more for aesthetic reasons. I like blue a lot, and a lot of the trims and additional colors really looked good with the dark blue body, but I really don’t care for the Blue Dragonflight almost at all. They’re easily my least favorite of the five, but the contrast of blue scales to light blue horns/accents and piercing orange eyes looked great on my Dracthyr so that’s what I went with. I may still be playing around with it a lot though, I’m indecisive.
My main color is purple, my secondary is green, & my armor is … um … I think blue. I think I erased all my markings & chose no horns. I picked purple & green because they’re my favorite colors, forgot entirely about green being the “healer’s color” but intended to do mostly DPS anyway
