Background Colour?

Helllo Marcel. Sorry to have to bother you again.

But I ended up solving the button image problem by using the following short code:

[gwolle_gb button=”false”]

From there I was able to use Yellow Pencil and set the button I want to use in place of text for the preview button.

Anyway I don’t know how I missed this? But after I post a comment the comment is shown but you cannot read it because of the white background as showin the following screenshot.

So can you please tell me where and in which file I need to change this to a darker colour?

Thanks.
