Pink dress shirts for men have been ok in the US for everyone for about 12 years. If you wear a pink dress shirt, the stares and comments you get will probably be all positive.
That being said, it is true that in many parts of this very large country, wearing other bright colors or patterns might bring comments or questionable looks. This is unfortunate. We need more trendsetters to change this - so please wear anything you like. If you look good in it, and you feel comfortable in it, others will be ok with it too (and may wind up wearing something similar themselves in the future!)
