Remarks
getcolor returns the current drawing color.
The drawing color is the value to which pixels are set when lines and so on are drawn. For example, in CGACO mode, the palette contains four colors: the background color, light green, light red, and yellow. In this mode, if getcolor returns 1, the current drawing color is light green.
Return value
getcolor returns the current drawing color.
