changing the color display.

Minimizing browser dither
Using colors in the Web palette ensures that colors
won't dither when displayed in browsers on either
Windows or Macintosh operating systems capable
of displaying at least 256 colors. When creating an
original image, you can use the color picker to
choose Web-safe colors. (See "Using Web-safe
colors" on page 78.)

the dither patterns with other images.
