I found this infographic when I was redesigning this site (it's a little dated but relevant nonetheless). I have a personal preference for green, but as this infographic shows, there are a few very common colors that are used in corporate palettes. I ended up deciding on red and blue for that reason, though I used a seasonal color palette (with hex colors from this site) as an homage to my wife who is attentive to such things. Let me know what you think about use of color on websites and this infographic.
