In the beginning of the Internet it was said to use only 16 main colors or 216 "web safe" colors. This was due to the limitations of graphic cards at the time beeing. Todays graphic cards can easily show 16.7 million different colors (24 bit) so we don't need to be considerate of it anymore.

Still, you should keep in mind that many people use wrong settings on their monitors. Often it is too dark or too bright. A nice orange color on your monitor might be an ugly, dirty yellow on another person's monitor.
