How to change font color of a widget

Hello. I created a widget area right below the header and I'm trying to set the font color for that widget to something different from the rest of the widgets. My site http://kpopfever.com.

I tried adding this into the CSS insert, but it doesn't change the font color even though it successfully increases the font size.
div#text-8{
font-size: 13px;
color: #ffffff;
}

I've set the font color from ATO-Style Widgets, but now I have all the widgets set with a white font and that's not what I want. Can someone please tell me what I'm doing wrong. Thank you.

P.S. - I searched the forum to find this answer, but nothing worked for me.
