I've recently changed my office theme colors (and also office version from 2010 to 2016) and all of a sudden the default colors of all charts look crap. https://goo.gl/photos/PtVvvrQfVPGwAPG3A
Apparently all font coloring and chart gridlines defaults to a light shade of your chosen color for "Text/Background - Dark 1", which in my case is a dark teal. Anyone knows how to change this default setting without having to actually change my office theme colors? And anyhow, even if I do change theme colors, how to get a dark shade instead of the lighter choice?

Thanks for all input!
