A web color is usually specified as a 6-digits hexadecimal
number. The 6-digitsrepresentsthe Red Green Blue value of the
color, commonly referred as the RGB
values. Even though there are6 digits on each number, these six
digits are actuallythreeseparate pairs of numbers,
specifically: The first two digits are the Red (R) value of
the color.
The next two digits are the Green (G) value ofthe
color. The last two digits are the Blue(B) value of the
color.You might attempt to interpret all six digits as a whole, but
that willbe
meaningless. Instead, you should always break up the six digits
into RGB values like
CCFF00 CCFF33 CCFF66 CCFF99 CCFFCC CCFFFF
FF 0000 FF 0033 FF 0066 FF 0099 FF00CC FF00FF

WHAT ARE THE WEB SAFE COLORS?
Web safe colors are sets of colors that willnot bealtered
(dithered) whenshown onbrowsers running on a 256-color browser.
These sets of colors are initially selectedbyNetscape for use on
their browsers.
Web safe colors seem to beirrelevant for today'scomputers, but
back when the webwas invented, many people still use graphics card
which supports only 256 colors (or less). In fact, even today
(April 2000), Netscape browsers seems to still have some
problems when displaying colors; while Internet Explorer seems
to have better color handling (for more on this
discrepancy,see the last section on this document).
You might be wondering what is so special about the number 256.
This is a topic that Iwon'tget into, but the short answer is
because 255 is the maximum valuesfor an 8 bit
number(i.e.:255 is 28
).
Of the 256 possible colors, there are 216 that is designatedto
be web safe colors; they
are shown on the table above. The remaining 32 colors are used
bythe operatingsystem (such as Windows 95, or MacOS) and are
reserved for the color of title bar,desktop, menu bar, etc.
