Color problem with font and font size selection dropdown

[Gota]

Okay, so I was able to change almost everything color related to our theme and I think it looks a lot more individual now but there is still one problem remaining. As you can see in the image below the selection area for font name and size are both still white and you can't see anything because the general font color of the site is white as well. I managed to solve this problem with anything else that had the same one but I couldn't find a solution for this one. If anyone knows a solution on how to make the font for these two visible again, I'd appreciate it.

Add this custom CSS in css_additional template in AdminCP or in Sitebuilder > Style > CSS Editor.

.cke_panel_frame {
background: #000; /* change color as needed */
}

That finally solved it (and it even looks better than before), thanks a lot!
