Random Observation
Applejack and Scootaloo have almost identical coat colors.
O__O
Applejack mane = Fluttershy coat = Rainbow Dash yellow mane stripe
Fluttershy mane = Pinkie Pie coat = Sweetie Belle mane (pink)
Applejack body outline = Scootaloo outline = Rainbow Dash orange mane stripe
Twilight pink mane stripe = Pinkie mane
Twilight purple mane stripe = Rainbow Dash purple mane stripe
I may have missed some, but the point is that colorful ponies often share colors in their palettes and that’s pretty cool! (Except Rarity, because she’s one of a kind.)
