+	graphics mode, the display attributes (set by <SI> code
+	sequences) work slightly differently: the background color is
+	ignored, and the foreground colors are the 16 colors specified
+	in the image file.  For that reason, ppmtolss16 allows you to
+	specify that certain colors should be assigned to specific
+	color indicies.
