The register# indicates the number of the register whose default
values
are to be altered. The color# indicates the color to which
the register indicated is to be set. The sixteen available colors are
listed in Table 9-3 with their associated SETCOLOR numbers.
The
luminance i ndi cates the brightness value of the color.
Luminance can range from 0 (darkest) to 14 (brightest). Odd

even value. By combining the different col or and l uminance
va lues, as many as 128 different shades of color can be created.
