+• colo[u]r <colour>  set the map colour when selecting a map; this option overrides the specified colour palette ONLY when the layout specifies colour map-fg [map], [scrap] or [<colour>].  It has no effect when the layout specifies colour map-fg [altitude].  It has no effect when the layout specifies colour map-fg [topo-date] or [explo-date], for the scraps whose associated surveys have dates assigned.
+In summary:
+Select map -colour overrides layout or lookup colour map-fg statements when…
+  * colour map-fg [r g b]
+  * colour map-fg scrap
+  * colour map-fg map
+Select map -colour does not override layout or lookup colour map-fg statements when…
+  * colour map-fg altitude
+  * colour map-fg topo-date, unless the map has no date
+  * colour map-fg explo-date, unless the map has no date
