(Ask a non-baseball-fan/non-purist with an eye.) I do! And I ask myself! The hat? Well, on a small article of clothing, contrast between brights distracts; this is all the more problematic when your alternate/complementary color is brighter. I would say it clashes, except orange and royal are perfectly complimentary colors. It's pretty obvious here, the orange-brimmed hat at best gets in your eye's way, and at worst draws your eye away from the logo. Something that's non-functional-- taking attention away from what you're trying to underscore-- epitomizes bad design, doesn't it? I'd say complimentary colors on alternate panels is a solid design basic. Your point that the brim distracts from the logo is not lost, however. It is, nonethess, a giant leap forward from black hat/blue brim with the orange and blue insignia. Baseball aside... white dress, blue hat: classic, adorable, fetching, looks great against any background --- but certainly a green one --- and catches both natural and artificial white light in a way that makes you celebrate creation. And let's not forget the calumnious tradition that has left solid color alternates traditionally worn on Sundays, when the brightness of daytime baseball would flatter the whites the best. Alternative, the blue dress and blue hat... a garish, obnoxious attention grab that works best indoors under the jaundiced miasma of artificial yellow. It's an outdoor summer sport, that looks best with an outdoor summer look, where bright saturated colors work best to accessorize. And I think the culture of the team is best served when they honor their basics, and introduce variety in the details, rather than the foundation.
