What's in a name? Milky & Pinky

Been wondering things for some time now- why is it that the g1 Japanese Takara ponies, the main two, at least- Milky and Pinky, are named as they are? It could be entirely random, but I really don't like that conclusion, quite frankly. Their little sisters are named "Lily" and "Popo", and their four adult friends are named after different types of hairstyles: "Ami Ami", "Sara Sara", "Fuwa Fuwa", and "Kuru Kuru". Seeing as how the entire line of Takara ponies translate to fashionable pony", I decided to do some digging as to why Milky and Pinky are named how they are. 

 

Since the Takara Osharena ponies were released in Japan in 1985, I can only assume that their names would have some sort of reference and influence in Japanese culture around this time, or earlier. Why "Milky" and "Pinky", specifically? Well- seeing as how the toyline's name is based off stylish ponies, I can personally only assume that Milky, at the very least, could have been a name that was inspired and influenced by the Japanese Lolita brand, Milk- which was started in 1970, and paved the way for the fashion trend to grow exponentially out of Harajuku. Similarly, "Pinky" could've manifested and been inspired by the early Otome brand, Pink House, which was founded by Isao Kaneko in 1973. Of course, this is all merely my own speculation, (that may be fueled by my own personal biases) but I feel like it provides a reasonably enough explanation. If anyone has any other theories as to how these names possibly came to be, then I would love to discuss them.
