Color Palettes Test
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 y if all
the squares are the correct colors; otherwise type n.
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 individual color boxes are three lines that show the intensity of each color. Type
r, g, or b to adjust the intensity of the corresponding color; then press the right-arrow key to increase the color intensity,
or press the left-arrow key to decrease the intensity. The RGB box should be able to display 262,144 different colors
when you adjust the intensity levels of red, green, and blue. Type y if all the squares are the correct colors; otherwise
type n.
Solid Colors Test
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 y if all the pixels were
present and if the correct colors were displayed; otherwise, type n.
