The band palette is calibrated against a plain basemap. Over the Esri
imagery the 60m navy and the 70cm olive all but disappear, and 20m
yellow goes over the deserts — and the palette only earns its keep for
somebody watching several bands at once, which most operators are not.
So a colour input beside the basemap buttons, where it belongs: the two
are one decision, since the palette that reads well on the plain map is
the one that vanishes over the ground. Empty means per band, which stays
the default, and the reset arrow appears only once something is set. It
opens on the crimson the home marker already uses, that being chosen to
hold up on any basemap.
With a colour forced the legend keeps the band NAMES and drops the
swatches: which bands are up is still worth knowing, a colour key that
maps to nothing is not.
Stored as a portable UI pref, like the grid map's own fills, so it
travels with data/.
