It's so weird that the show staff didn't make either one or the other as the aura colour. I suppose in some ponies' cases, like DJ Pon-3, the pony has a black cutie mark, and that would look evil as an aura. So they just made hers blue like her mane. That's another thing, aura colours can also match mane and coat colours (mainly in background ponies).
