Alter appointment calendar contrast

[nitric22]

I saw several threads from 2019, but none recently, related to the near impossible to distinguish white and grey color scheme used in the calendar on desktop browsers. This is true in both Edge and Chrome. It would be a massive help if the unavailable grey were darkened just a small amount. As it stands I struggle to clearly see the open availability that is set.
