Feature Request: Different call out color for dark and light mode

[Bloe1901]

Hi,
I would really appreciate an option to add different colors for the call outs in different modes. The higher contrast color for the icon/ background in dark mode is too low contrast in light mode and vice versa. The background opacity setting is not enough to fix this contrast issue. And I think this feature would make a huge improvement overall to accessibility if added.
Thank you !
