Did you try this, <div>Create a file named "gtk.css" under "~/.config/gtk-3.0/" with the following content, .toolbar { background-color: #dedede; } On Friday, 21 February 2014, Christian Dysthe <<a href="mailto:cdysthe@gmail.com">cdysthe@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi, I have spent a lot of time on trying to figure out why there's black background around all emails in Evolution after upgrading to 3.10 using the PPA. First I thought it was the theme I am using (Moka) but it turns out that the black background in Evolution is present in any GTK theme I have installed, so it's not the one particular theme.
