I added a link to the 'web style guide' found under BE 170 resources. This link not only talks about the use of color but about all elements need to create a web site. Color is one important element that creates interest but, a well planned site will generate return traffic.

Color wheel

Different colors are associated with different moods and emotions. When designing your sites one thing you should think about is the mood you want your viewer to feel. Below is a list of a few basic colors and the emotions they are associated with:
Blue - is one of the most used colors on the web. This is because it is a safe color and the mood it conveys are mostly good. Blue can represent peace, tranquility, reliability, trust, honesty, cleanliness and clarity. Blue can also represent depression, having the 'blues'.
Green - Has always been associated with nature. It also can represent environment, health, luck and youth. In some cultures it represents distrust and danger.
Yellow - Is a very happy color and represents joy, happiness, the sun, and friendship. It can also represent cowardice and illness.
Orange - Can convey warmth and energy. Orange can be a good attention grabber when used correctly.
Red - Stands for danger and caution. Good things include love and warmth. Red is a good attention grabber or can be used for focal points on a website.
Purple - Is a mysterious, creative color. It's also associated with royalty and exotic items.
Pink - Is thought of as a feminine color and is also associated with babies and childhood.
Black - Text on white background is the easiest to read. Attention grabbing colors such as red and orange stand out more if on a black background.
White - Represents purity and goodness. It can also represent coldness and winter.
