Where can I change/add the colors available for Calendar Overlay in SharePoint 2010? We have a branded site (using our own Site Theme). I only have 2 choices for colors when I create calendar overlays: Dark Red, #5a041c listed 7 times and Gray-50%, #7f7f7 listed 2 times. On our OOB Test Site I have 9 different color choices. Where do I add more colors to our branded site?
