255  * Reset the color pair, e.g., to whatever color pair 0 is.
275  * Reset color pairs and definitions.  Actually we do both more to accommodate
277  * someone has changed the color definitions.
334 	 * Without ext-colors, we cannot represent more than 256 color pairs.
346 	     * allow for default-color as a component of a color-pair.
