These color
charts contain an approximation (the numbers are exact; the
colors as close as technology can get them) of a color
palette that will not dither when viewed on the web. The
center 6 columns contain the 216 non-dithering colors; the
outer two columns (pure shades of red, green, blue and
black) are for reference.
I also have my 'Color Checker', a javascript utility that
will let you experiment with different color combinations,
a lesson on the hexadecimal number system, a set of
important color definitions, and, last but definitely not
least, links to VisiBone, undoubtedly
the Web's most complete source of color and web
information. (in my opinion anyway...)
