In the GameCube 20th anniversary VGC interview, it was revealed that former Nintendo of America VP of marketing Perrin Kaplan thought that there was one aspect of the GameCube that he and NoA were not fond of and made them extremely nervous about the console's perception:

"We actually suggested that the purple was not the best [console color] to start with and [Japan] said, ‘no, we’re going to use that [...] Then we pushed for black and silver, because I think in the US nobody had ever really done the purple colour before. [...] It wasn’t that you couldn’t bring out hardware that was a different colour, it was just a very… ‘female’ looking colour. It just didn’t feel masculine, I think. I remember us being very nervous at E3 that we were going to get bad press purely based on the colour.”

Nintendo of Europe was not to easy on the color either with the company's veteran Shelly Peirce revealing that one person referred to it as a "Fischer-Price record player". However Pierce remained optimistic because he felt that what Nintendo was doing was uniquely different than the competition.
