+X/Open defines no error conditions.
+This implementation will return \fBERR\fR on attempts to
+use color values outside the range 0 to COLORS-1
+(except for the default colors extension),
+or use color pairs outside the range 0 to COLOR_PAIR-1.
+Color values used in \fBinit_color\fP must be in the range 0 to 1000.
+An error is returned from all functions
+if the terminal has not been initialized.
+An error is returned from secondary functions such as \fBinit_pair\fP
+if \fBstart_color\fP was not called.

+.TP 5
+\fBinit_color\fP
+returns an error if the terminal does not support
+this feature, e.g., if the \fIinitialize_color\fP capability is absent
+from the terminal description.
+.TP 5
+\fBstart_color\fP
+returns an error
+If the color table cannot be allocated.
