That is just silly bro. I suppose you are one of those people that think the iPhone is for "men" and the iPod Touch is for "children" despite the devices both function the same excluding phone features.
Really the red looks pretty nice when you look at it outside of Apple's digital images (which I don't really understand why they continue to use these digital photos that look like crap compared to the actual product).
Silver/Black are the most standard colors, they don't stick out and they are definitely less flashy than the other colors but I don't think it makes them childish if one were to get blue/red.
Anyway you're obviously entitled to your own opinion and I respect that. Just sharing my view.
As far as the best color goes, Silver wins in my opinion. The black (charcoal or slate as they call it) just doesn't look very good this year which is surprising because black is usually the color I choose. Red is a fairly close second this year with the slate coming in 3rd.
