The best color for a website will depend on the intention of the site (commodities, self-empowerment, entertainment), the time of year (summer, spring, fall), the audience of the site (children, teens, men, women) and where the color is placed (title, background, text, header, etc). Research has found that women don't respond well to orange, brown, and grey but favor blue, green, or purple. Men share a dislike of orange and brown and also prefer blue or black. People tend to trust when they see the color blue. The rest are predictable such as yellow for caution and green for the environment. Green is also thought to be the best color for conversion elements such as submit buttons. White is generally best used for background and black for information. Again, though, there is a definite art to combinations.
