Five different default colors are available in graphi cs modes 1
and 2. These
correspond to color registers 0 through 4 (see Table
9-2).
Color register 4 controls the background and border colors. The
default color is color 0 with a luminance of O. This sets the
background and border colors to black . The following
SETCOLOR statement,
SETCOLOR 4,0,4
would set the border and background colors to grey in graphics
modes 1 and
2. SETCOLOR 4,2,4 would set the background and
border colors to orange.
In graphics modes 1 and 2, the color of the characters output in
the graphics window depends on the type of character. The
color registers and default colors used for each type of character
are
summarized in Table 9-5.
