Ok remember where you changed the copyright text color? Same section has the bottom bar called the footer, controls. Footer_background is what you're looking for. Click on the little color tab. Pick the color you want then click save. You're done with that one.
Moving right along...
Subtitles? From the description and the image that's the breadcrumbs. They're links and as such have to be handled differently from regular text. You can use the links stylevars but you'll change the color of links all over the forum. You have to attack those directly using a css edit.
Put this code in the additional.css then click save and reload.

/* Makes the text in the breadcrumbs white */
.breadcrumb .navbit > a, .breadcrumb .lastnavbit > span {
color: white;
}

/* Makes breadcrumbs hover color red */
.breadcrumb .navbit a:hover {
color: red;
}

Ok done with that.
Next one I have no clue. You tell me and we'll both know.
Text editor background? If your forum is above 4.1.2 then you have the ckeditor and some one with that will have to tell you what to do. I'm on 4.1.2 and don't have that.

Now please stop bumping this thread.
