When selecting colors, try to pick ones that Netscape and
Internet Explorer do not dither. Dithering is basically
a process of making one color by mixing pixels of other colors,
as opposed to setting the pixel to the color you want. This
is not always a good effect.
There is a minor problem for us when selecting colors. If
your reader has their video set for 256 colors, then Netscape
will only display the 216 colors you
see on this tall chart up and to the left. Here is the basic concept
of what are called the SAFE COLORS.
We previously mentioned that there are 256 X 256 X 256 colors
(around 16 million), but if a video card is set to 256 colors,
something has to give. What gave is most of the colors! Here
is how it exactly how to figure out if your color is safe.
In HEX (see below), each red, green, or blue component
must start with:
00 or 33 or 66 or 99 or CC or FF
So, instead of 256 levels of red, green and blue, you have only
6. This results in 6 X 6 X 6 or 216 colors!

Another item I have come across is an incredible piece of mousecandy!
All the safe colors arranged on a round mousepad, with the Hex-to-Decicmal
equivalents around the edge. When I got mine, I washed down the mouse
before using it. Check out
