With most monitors supporting 24 or 32 bit color, web developers have been using every variation of hue, saturation, and intensity possible. Or so it seems. This is necessary when creating real life images and perhaps for other reasons. But, monitors don't render color the same. Age, contrast and brigthness settings, brand, LCD v. CRT, and other factors cause remarkable differences in the actual color displayed. So all of the care in color selection may be lost to a large number of users.

The following chart shows colors using power setting increments of 20% and 50%. Differences between the colors will be show on most monitors. Selecting one of these colors, if they will meet your needs, will give you good cross platform results
