As to the gender issue I don't see it as a problem. Yea of course pink and purple ponies are seen as feminine, but that is just a generalization.
Who says pink is a feminine color, and blue a masculine? Society does.
Actually, the color pink was associated with masculinity for many years.
An article in the trade publication Earnshaw's Infants' Department in June 1918 said: "The generally accepted rule is pink for the boys, and blue for the girls. The reason is that pink, being a more decided and stronger color, is more suitable for the boy, while blue, which is more delicate and dainty, is prettier for the girl."[18] From then until the 1940s, pink was considered appropriate for boys because being related to red it was the more masculine and decided color, while blue was considered appropriate for girls because it was the more delicate and dainty color, or related to the Virgin Mary.[19][20][21] Since the 1940s, the societal norm was inverted; pink became considered appropriate for girls and blue appropriate for boys, a practice that has continued into the 21st century.

As well, the color purple was associated with royalty.
The actual color of Tyrian purple, the original color purple from which the name purple is derived, is the color of a dye extracted from a mollusk found on the shores of the city of Tyre in ancient Phoenicia (present day Lebanon) that in classical antiquity became a symbol of royalty because only the very wealthy could afford it. Therefore, Tyrian purple was also called imperial purple.
Tyrian purple may have been discovered as early as the time of the Minoan civilization. Alexander the Great (when giving imperial audiences as the Emperor of the Macedonian Empire), the emperor of the Seleucid Empire, and the kings of Ptolemaic Egypt all wore Tyrian purple. The imperial robes of Roman emperors were Tyrian purple trimmed in metallic gold thread. The badge of office of a Roman Senator was a stripe of Tyrian purple on their white toga.[13] Tyrian purple was continued in use by the emperors of the Eastern Roman Empire until its final collapse in 1453.
