Another thing that can be good to keep in mind when making color selections is color blindness. Some 8% of the population has some form of color blindness, and by choosing the wrong colors, you can make your page virtually unreadable for them. There are some colors which are worse than others-- for instance, red and green. Blues and yellows are usually better to use for this reason, and you should make sure that there is a strong contrast between a text and its background. Also, make your design so that color is not the only visual cue.
