examples of Cutie Marks.
Cutie Marks are a type of magical, picture-like symbol that's most commonly seen and presented in Equestrian Ponies.
Description
Cutie marks come in a wide variety of shapes and colors. Cutie marks are often a set of two or three objects or animals, and usually feature between one and three colors. For example, Rarity, Pinkie Pie, Fluttershy, and Applejack all have cutie marks with three objects and all of their designs have only two colors. One of the few ponies with a cutie mark with more than three colors is Rainbow Dash, whose rainbow lightning bolt has four. The other ponies with four or five-colored cutie marks feature a more detailed image, so many of the colors are only different to allow for shading.
Starlight Glimmer uses a spell that removes a pony's cutie mark, replacing it with an equals sign. This adds a gray tone to the victim's color and effectively disrupts the talents associated with the cutie mark. (The equals mark Starlight Glimmer dons is a fake, as she reveals in the second part to have simply painted it over her real cutie mark to hide it.) This spell also demonstrates that cutie marks that have been separated from their owner can be stored, as Starlight Glimmer holds the missing marks in jars or in the Cutie Vault. When the marks are released, they return to the ponies they originally belonged to.
While this is primarily a Pony-related spell, other creatures outside the three main races have been shown to gain Cutie Marks: Zecora's mark on her flank is often said as a Cutie Mark, although she is a zebra. Jasper, Peridot, Amethyst, and Connie II also possess Cutie Marks, albeit on their cheeks instead of their flanks.
