What "other" CSS template? Are you running a style you did yourself or one that you downloaded (paid or free). There is always the possibility that the style author created a custom template to control some aspects of that... and if so, you need to edit it in that template (but the next update of the style it might be overwritten - ergo the need to do all custom edits on paid/free styles in a child style of the paid/free style).
@Tracy Perry I figured since @Brogan's suggestion included !important, those colors were already defined elsewhere. I thought I had already seen them when playing with palettes in AdminCP, but I could be wrong.
