Something I just remembered is that the dress isn’t even dark blue nor white, but a lighter blue (or so I read). I found an image that shows what I mean:  

@Meanlucario  
Uh-oh. In this bird guide the plumages suddenly got mixed up!

@Depressed Knoll  
Looking at that image, I would call it a blue dress with black trim.  
All the black elements appear to be lace trim, and thus I would not consider it to be the base colour.

@Depressed Knoll  
Looks clearer than most pictures of it.

I think this is the dress in question.  

@MLP-Silver-Quill  
really? that’s neat!

@Background Pony Number 17  
oh yeah now I remember, so weird that they used the same models later in the ep as there canon colors. I wonder if that was a accident?

@Fimbulvinter  
I see it as B&B as well. Best part is that it’s apparently neither of those combos, though I forget what the actual combination was.

@MLP-Silver-Quill  
I remember that dress. I always though the debate was about if it was a blue dress with black stripes or a black dress with blue stripes. Didn’t know there was supposed to be a white and gold alternate view for it.  
So I suppose that means I see it as blue and black.

Archer was a background appearance in the Perfect Stallion song, and Hopper never appeared a second time, according to this site.

 
In “Call of the Cutie”, Scootaloo and Sweetie Belle were given recolors in the classroom scenes to obscure the fact that they were Apple Bloom’s classmates before their big reveal at the climax of the episode.
 
“Scoota-blue” was later dubbed Archer due to her cutie mark.  
“Greenie Belle” was given the fan names Sun Glimmer and Star Hopper.
 
Archer showed up in later episodes, but I don’t think “Greenie Belle” had more than this one appearance.

@MLP-Silver-Quill
 
Wow, you learn something new each day then, also I just LOVE how Scootaloo and Sweetie-Belle were able to pull one over on Pinkie Pie and Applebloom like that, it was just PERFECT.

After successfully completing your first Cutie Map mission in “Surf and/or Turf,” you girls have certainly earned the opportunity to do one of Pinkie Pie’s goodnights.

This was beautiful XD

There was an actual dress photo circulating the net a few years ago. Depending on your eye it would look either white and gold or blue and black. There is, of course, a wiki page on it. Which means it must be true!

It was an interesting study in human nature. People couldn’t just accept that their eyes behaved differently. There were arguments over it.

@neo4812  
Go watch Call of the Cuties and see who’s in the classroom with Bloom.

is this part of a meme? this is funny as hell I just want to know if this is part of a meme.
