How can I change the color scheme, fonts etc for the filter widget in the Dashboard Theme? Specifically for each individual filter added with a filter expression. I was able to update the filter widget background color by adding .jimu-widget-filter css rules in the jimu-theme-override.css file in the "light" style folder. Looking at the attached image, I would like to at least turn the grey "Test" filter background to match the blue background for the Filter Widget, as well as edit the fonts.
