Bits of Color
Remember, the number of unique colors that can be displayed on a computer
screen is over 16 million. To see this many possible colors, your system
has to be capable of handling 24 bits of color, or 8 bits each for the
red, green and blue values.
More bits allow for
more colors to be displayed. Fewer total bits available in the system
configuration yield fewer colors, as shown below:

Your Screen Display
The number of colors which can see on your screen is determined by your
system's graphics card and the driver settings for it. An SVGA color monitor
with a graphics card having 2 megabytes of RAM or more, should allow display
choices up to True Color or 16 million colors. If your system does not support
the True Color or 24 bit option, it is still preferable to use the highest
color setting available. The 65k or 16 bit setting is optimal and
should display all web colors and graphics correctly. Most computers sold
over the last few years have a default setting of 16 bits.. (About Screen
Resolution)
Here are suggestions for checking and correcting your display in Windows
95/98 and, probably, the newer Microsoft operating systems as well:
Increase the color depth of your display:
- Select: My Computer>Control Panel>Display>Settings.
OR
- Right click anywhere on your desktop and select Properties at the
bottom. Click on the Settings tab at the top. Use the sliders to make
adjustments. Your video card manufacturer is shown here, too.
If you don't see the option to increase your color display, you may have
to download the latest video drivers from the manufacturer's web site.
Please contact your
PC or video card vendor for more information.
