how to specify notmuch colors in emacs24

[David Belohrad]

Hi All,

thanks for extensive answers on this thread. The plum-1 and other
definitions are coming from 'tango-dark' theme of emacs 24, which I
wanted to modify. I understood hence, that the two ways of settings the
colors (notmuch/emacs24) are so far somehow incompatible and hence there
is no way how to specify the notmuch colors the emacs24 way.

many thanks
.d.
