I have a light sensitivity problem with my eyes, so I find screens easiest to view when matching dark/light mode with my surroundings (night or day respectively).
This works fine in theory, but with some apps the dark mode is very black. This makes the white text uncomfortable to read and can lead to an afterimage when reading in a low-light (but not extremely dark) environment.
Alternative dark/light themes, such as OKSolar (https://meat.io/oksolar) can help with this a lot. Or even just a toggle that enables a slightly less black dark mode.
Hopefully there’s some plans to implement something like this, as I know it can impact a decent amount of people.
Grey text for black theme would be awesome too.
The latest TestFlight version seems to have this option!
