The Internet-Safe Color Palette

If you specify a color that can't be displayed on your system, the browser will try to produce a similar color by dithering, or creating a textured background with elements of each of the two closest colors. Sounds nice, but it isn't; you end up with a pebbly background that can make your text completely unreadable. The trick is to use the so-called Internet-safe color choices, if you're specifying color with a hexidecimal value. It's pretty easy: just remember that each of the three basic colors (red, green, blue) should be chosen from 00 33 66 99 CC FF and you'll be fine. The following table shows a display of all the Internet-safe colors.
