Well, in general overrides/tweaks it's possible:
\new FretBoards {
\override FretBoard.color = #red
a
\tweak color #'(0.9 0.5 0.2)
bes
}
In a verbose fret diagram like
\markup \fret-diagram-verbose #'((place-fret 3 3 3 blue))
you would need to quasiquote/unquote like
\markup \fret-diagram-verbose #`((place-fret 3 3 3 ,blue))
At the time I implemented dot colors I intended to not confuse users
with this syntax.
Probably I should rethink ...
