 \fBRemind\fR doesn't treat black or white specially and some reminders
 may be rendered invisible.
+.PP
+Some terminals (such as "xterm") understand additional escape sequences
+that allow for specification of 256 different colors.  If you supply
+a value of 2, 3 or 4 for \fIn\fR, then \fBRemind\fR uses these enhanced
+escape sequences to more closely approximate colors.  A value of 2
+tells \fBRemind\fR that the terminal background is dark, 3 that it is
+light, and 4 that \fBRemind\fR should not do anything special to
+compensate for the background.
