What I did:
Used calendar in Dark Mode in Mojave with ‘Graphite’ set as the accent color (in General settings).
Got a white ‘day number’ over a light-grey background because Agenda used my ‘Graphite’ setting, but unfortunately doesn’t play nice here.
What I expected:
Darker grey or black number? Maybe not possible and just have to suffice if ‘Graphite’ highlight color selected?
Things that might be helpful to know (Agenda version, OS and model, etc):
Mojave, Dark Mode, Graphite accent color, calendar ‘day number’.
