Non-Dithering Colors
Here is a chart of 216 "non-dithering"
colors. What that means is that the colors will look like
the color you ask for on all browsers and all computer screen
resolution settings assuming a video color capability of at
least 256 colors. Tests have shown that Internet Explorer
used in the Windows platform does not properly render four
of these colors and they are marked with an asterisk (*).
Note: If your monitor is misaligned your colors may appear
dull or too bright. Click here

What is Dithering?
We've all seen colors created
by what appeared to be one solid color and then a few lighter
colored dots blended in. The colors may look blotchy or just
full of dots but not a solid color. We have seen the same
problem when printing things as well. Some colors are made
up of multiple colors sprinkled together so that your eye
blends or dithers the colors, so that you see only one. Unfortunately
with some of the resolution and color settings used we don't
see the intended blend, but rather the dots and splotches.
It comes from placing the dots together and not truly mixing
them.
The colors in the following
chart give smooth colors on web pages because these are the
216 colors used to make up the Windows and Macintosh color
palettes. All the other colors are achieved by mixing or dithering
these colors.
The numbers shown in each color swatch are
the hexadecimal numbers you need to use in your web page to
display the corresponding color. Note that each one is made
using the hexadecimal values 00, 33, 66, 99, CC, and FF which
represent corresponding intensities of the three primary colors
RED, GREEN, and BLUE. The value 00 represents a total absense
of that particular color and the value FF represents all you
can get of it.
Hexadecimal is a numbering system used with
computers and provides a way to represent the values formed
by four bits at a time with two hexadecimal values representing
16 bits. In hexadecimal you count 0, 1, 2, 3, 4, 5, 6, 7,
8, 9, A, B, C, D, E, F.
