Colgate

Colgate is the fan-given name for a unicorn mare with a light blue coat, an ice-colored mane with a dark blue streak, and a cutie mark of an hourglass. She is named after the toothpaste company due to her color scheme's resemblance to toothpaste. Other names for her include Aquafresh and Minty Fresh. A portion of the fan base relates her to the British TV series Doctor Who due to her hourglass cutie mark, and has given her names such as Romana, Jenne, or TARDIE.

Mystery Pack toy name
In November 2011, a mystery pack glitter toy named "Minuette" was released by Hasbro. It uses the Twilight Sparkle mold but features a color scheme and cutie mark highly similar to Colgate's. This has led to the acceptance of "Minuette" as the pony's current most official name, though much of the fan base still uses the fan-made names for her.
