The Color Palettes Test checks the video subsystem’s ability to display all available
colors. The test displays two screens that allow you to check the quality of different
shades of the basic colors and to test the monitor’s ability to vary the intensity of
these colors.
The first screen contains four sets of 64 squares, one for gray and one for each of the
three basic colors (red, green, and blue). Each square contains a different shade of its
associated color, ranging from very light to very dark. Type

if all the squares are the
correct colors; otherwise type
Q

The second screen is the red/green/blue (RGB) color combination screen. This screen
allows you to test the monitor’s ability to increase or decrease the intensity of the
three basic colors.
The RGB color combination screen displays an RGB box in the top center of the
screen with individual red, green, and blue boxes beneath it. Underneath the individ-
ual color boxes are three lines that show the intensity of each color. Type

The Solid Colors Test checks whether the video subsystem is displaying the correct
colors. This test also lets you check for missing pixels. When this test is running, four
screens appear sequentially—a red screen, a green screen, a blue screen, and a
white screen. Check each screen for missing pixels, and verify that the correct color is
being displayed.
When the test is complete, a message asks if you are satisfied with the quality of the
colors. Type
\
if all the pixels were present and if the correct colors were displayed;
otherwise, type
Q
