[Users] Message text is gray, not black.

[Henry Carmichael]

This is true of all messages received by Claws-Mail.

In the message display area, the header labels,
(From:, To:, Subject:, Date:, Reply-To:)
are in black letters (not bold). The contents of the several labels are
green. The text of the message is in gray letters, less dark than the
header labels. Seeing that the background is white, although the text
of the message is of great interest, it is difficult to read since the
contrast is low.
Is there a way to increase the darkness of of the text? Or, in other
words, to increase the contrast between message and background?

Thanks for help.
