This is just a common head cannon about Luna that I like. Where, when her power is drained from her, her hair and fur turns lighter and not as wavy. I know this wasn’t the case when tirek came along and the princesses gave their magic away to Twilight. However, I still love this idea and will be applying it to my version of Luna. Along with Celestia and Twilight, so look out for that when I draw them!
