Alright, I've decided on the name:
Alaula [A-loo-la]
@Jalaton first mentioned that her name would be Horizon since that is when the earth meets the sky, both times of the day. The meaning of Alaula is "light of dawn or sunset glow". And I thought that was clever, based on her back story which is the following: Her mother is a zebra; her father a pegasus. Grew up on land [Not in Equestria, probably where Zecora is from], but isn't afraid to venture up in the clouds. She doesn't have her cutie mark. She basically gave up on forcing herself to try and find it and thought it would come easier if it found her. She's traveled on hoof throughout Equestria rather than flying because having a close up look of something different is better than a general overview. Open to trying new things. Kind of embarrassed of ponies finding out she's a pegasus because the stripes and wings bewilder ponies more. However, she's not afraid of soaring in the clouds like the rest of the pegasi. She's around the same age as the mane 6. And I think her base coat would be the same or similar color as Pound Cake [The Cakes son] and that would be maybe her pallet with the dark brown. But thank you to everyone who gave me suggestions. Thanks to AnonBrony, Shadow Chase, and Jalaton! Don't know how to close this thread, but this thread is close.
