Personal preference.

personally i like it the red color, i think that is one or the most popular color of the world.

Red is a vibrant color, its just preference

I can't say definitively, as I am not American. But based on what I have seen, I would say that it is possibly seen as a little too bright. Are you aware that Chinese people are quite unusual in liking red so much? When I go there, I see much more red that I have seen in any other country. A correction: 'Do Americans like red?' or 'Do Americans like the color red?'

I live in the US, and in my opinion red is a pretty neutral color. Some people love it, some people don't but it doesn't have nearly as much cultural significance as it does in say Chinese culture. Generally in American culture, red signifies things such as love or passion, but otherwise there's no strong cultural connection.
