Default font color on metric vis is not very visible. #13548

Description of the problem including expected versus actual behavior: When you click play on after choosing to apply background color - the font for metric table is going grey. And it's not really very visible. Also I am not sure why green is getting applied as Background color. If it's set as default - where can I see that?
