Annoying orange lines?

I'm having a problem and I can't seem to figure out how to fix it, so I'm hoping one of you can help.

If you go to my journal, you'll notice there is an orange box around my entries and an orange line below the subject line, how can I change the color of that? I went through my layer and I couldn't find the hexadecimal color for that color orange anywhere so I don't know how it's showing up.

I tried adding:

.medLine {
background-color: #000000;
}

.entryDash {
background-color: #000000;
width: 100%;
height: 1px;
}

But neither change the background color. Thanks in advance.
