Readability

Text should have high contrast to be easily readable. This means that the color or brightness of the text should be as different as possible to the background it is placed upon. Black text on a white background is the best option.

Be sensitive to the commonly accepted rules of the Web. If you're offering professional services you shouldn't really use a light colored text on a dark background. For example, white on black. This is really only suitable for entertainment Web sites that want look trendy or cool.

Don't forget to pay particular attention to the needs of the millions of users who suffer from color, or low-vision deficiencies. There are many people who cannot differentiate between green and red when they're right next to each other.
