The Color Palettes Test checks the video subsystem’s ability to display all available col-
ors. The test displays two screens that allow you to check the quality of different
shades of the basic colors and to test the ability of the display or monitor 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

correct colors; otherwise, type
