I think if the Web site made professionally comfortable and beautiful. It does not matter what color he is.
It depends on your target audience and what you're trying to achieve with your website. Once you've determined that, try kuler.adobe.com to come up with color schemes.
Make sure your color combos make your text easy to read to be effective. And obviously use web-safe colors only.
I usually use 3-4 dim colors for background and interface and 1-2 bright colors for links or other stuff to make them stand out.
Colors that flow with the logo and can fit the mood or type of company or website. Ex. Hot topic would use dark colors that contrast well as to where Hello Kitty use's light colors that attract the attention of their customer base.
Take a look at these most successful sites www.google.com www.yahoo.com www.myspace.com www.facebook.com www.paypal.com www.ebay.com and many others They all use shades of "Blue" with call to actions at times in shades of orange and yellows. I have gone with reds www.tted.co.uk www.tvworlds.com Will that backfire on me? Only time will tell I guess, but my logo is black and red, but then Yahoo have a red logo and still use blue in most other areas.
The best color to use on a website is the same color that your logo have or the color that makes sense for your website. Try one of this websites: colorschemedesigner.com kuler.adobe.com Each color has a different meaning. "Google It" and try to discover them.
Glad to see a lot of input here. Thanks for all the responses. I'm still going to go with my years of marketing training, and like many members here have confirmed, stay away from too many dark colors unless your site is specific to that style, white, blue, different shades and not a lot more for the base, just add what you need where it goes and follow the psychology of marketing rules of thumb.
