When it comes to magic aura colour, Unicorns usually almost follow one of four reasons for the choice to colour them:

If most of the cutie mark is a light, friendly colour like blue, purple, yellow, light green, pink or orange, the Unicorn's magic will follow that. Examples include Cadance, Celestia, Twilight, Rarity and Fancy Pants.



If the Unicorn's cutie mark is the same colour as their mane or their magic is used before they get their cutie mark, then it matches their eyes. If the cutie mark is black (like DjPon-3) or another "evil" colour, their magic can't match it because it would make them look like a villain, so the creators make it match their eyes instead. Examples include Sunset Shimmer and Sweetie Belle.



If both the cutie mark and the eyes of the pony are the same colour, like Lyra, the creators either make the aura a different colour to both (possibly making it match their mane or coat colour) or the same as both.



And lastly, the aura might not match anything on the pony at all.
