Agreed with Mage.
While I never thought it was something necessary (I never made the color association either; if I even thought about it, I probably just saw it as the circle people being sharply contrasting colors for the sake of making it easy work for the eye to differentiate them), I do like that Octo was being kind enough to consider it. I can see why a person would make the gender connections even though I didn't.
So long as the originals remain, I don't think there's anything objectionable at all.
