Footer widget text color

I know this is the topic of much discussion, but when I search I don’t find anything that quite answers my question.

I’m trying to change the text color of the footer widgets. I can change the background color successfully (to #800000) but when I try to change the text to #eedcc3, it doesn’t work. (Site: https://www.stephaniecainonline.com/studytest/ )

I know rdell likes a solution involving Widget Builder, but I haven’t figured out how to use that to change the text color, and I also haven’t figured out how to make my Events Calendar plug-in work with Widget Builder (maybe it doesn’t). I know those are questions for the plug-in support–I’m just saying I don’t think the Widget Builder solution is for me.

Anyone have a suggestion?
