[Evolution] Change display behavior in the message window

[Andreas Kosubek <andreas kosubek googlemail com>]

Hello Evolution community,

i have a problem with Evolution 3.30.5-1.1 on Devuan Beowolf and Ascii
Linux. In the message display window, the default background color is
white and the color of html links too! How can i change the default
background color or/and the default color of displayed links?

Evolution is running under XFCE 4.12!

Thanks in advance for the support!

Andreas
