Pen Colors

GREG uses 24 colors for the pencils. Colors 0-7 are fixed colors, with the following values:

0 Black or White  (depending on window background color)
1 Red
2 Green
3 Blue
4 Cyan
5 Yellow
6 Magenta
7 White or Black  (the window background color)
Colors 8-23 can be modified by the user through the P_HUE, P_SATURATION, P_VALUE arrays and LUT /PEN command, in the same way as the bitmap colors. The default values for these arrays correspond to grey intensities from white to black.
