Yaru: gthumb has white background where black should be used

[pojntfx]

I just noticed the following issue after trying out the latest update (which looks really, really good btw!):

Due to the white color that's being used the text is hardly readable.

Thansk for the issue could you find out what Gtk class they use there? With the gtk inspector

[godlyranchdressing]

It's due to the hardcoded $sidebar_bg_color from f1315c4fb9d48c2d0075c943c86f9e58cf6c616e. @clobrano, you can try using the adjust-color SASS function.

I think we could probably just restore the old line and add:

$sidebar_bg_color: adjust-color($sidebar_bg_color, $red: 2);

That'll add 2 to the red value.

$sidebar_bg_color: darken($bg_color, 5%);
$sidebar_bg_color: adjust-color($sidebar_bg_color, $red: 2);
