Sort of related- as a newish parent, I was surprised at the variety of "colors of the rainbow" included in different foreign sourced toys, both in print and audio. Even translated to (decent sounding) English, many talking toys/books only seem to list 5 colors, and they're not always the same 5. But Red is always one of them. In case it needs to be stated, I was taught in the US that ROYGBIV is a fundamental constant of the universe.
