I wonder if she has any connections with the Alicorn Amulet which also has a red aura?
 
They never really explained the origins nor the working of that thing. While still making references and mentions to it as late as season 6 when Trixie appeared.

@Ebalosus  
However, in the case of a pony where we’ve not seen their magic, it is a good shot-in-the-dark if you are doing new art for them. It works about 75% of the time.
 
Also what’s wrong with your face?!

@SeraphimDawn 
I believe show staff said somewhere that her magic changed after she was redeemed. Remember, her geode is red now, too!
 
(Also, magic can match cutie marks.)

@SeraphimDawn
 

 
Uh, excuse me? What about Minuette’s magic aura? 

 
Or what about Celestia’s? 

 
Clearly their magic aura doesn’t match their eye color.

@SeraphimDawn 
or you could not and just go with what i said cus it’s easier.

@angrybrony 
I can also tout the theory that Sunset’s magic actually had grown while she was in the human world.

@Background Pony #6F41  
how does that mean anything?

@angrybrony 
@Background Pony #6F41 
oh my fucking god

@angrybrony 
Still more canon than Shimmer ^.

@SeraphimDawn 
i think it’s so they don’t mix up sunset’s aura with worst pony glimmer’s.

Sunset’s magic aura is red… interesting… even though her eyes are turquoise. 
I dunno about you guys, but I remember from the first movie her aura was the same as her eye colour.

This whole scene was adorable!

@Zharkaer 
Yeah, me neither. I’ve never used them.

@Sollace 
I don’t know why YayPonies continues to do that color correction thing. It was only ever good for the S1 iTunes rips.

@Zharkaer 
I (and my group) only use the unedited iTunes HD rip, so yeah.

@Sollace 
…As soon as we get an iTunes/good Discovery Family rip.

@Zharkaer 
I believe those are the colours we’ve had for a while (colour corrected). However the question still stands as to how accurate they really are. This scene puts it to rest as we can pick the full, unfiltered colours.

@DrakeyC 
Wish they had done so sooner.

@Zharkaer
 
No but there are those that do, and have done so before.

@DrakeyC 
Yes, though not everyone knows how to color correct like that.

@Zharkaer
 
There’s also the simple matter that color-correcting the night scenes allows one to perceive Sunset’s colors, since we know how the other ponies look in the light and from there can adjust the brightness to get Sunset’s color.

@DrakeyC 
To be fair, physical merchandise and its packaging is not really a good reference for colors

@Sollace
 
We’ve had proper colors for Sunset all along, she’s been in pony form on numerous pieces of merchandise, the Gameloft game, and some promotional materials.

Sunny you’re losing yourself

My reaction to this scene.
