undocumented colors in map

See attachment.

If you think that blocks labeled as extra1 and extra2

in default scheme are of the same color, then

1) you are mistaken, and

2) perhaps you can recognize more easily that difference in

substitute scheme.

Behavior is consistent in

- number of extra colors (two), and

- their locations in maps (unvarying over multiple analyses).
