Change text color in dark mode on Mac OSX

Maybe someone with a proper tool can confirm it but checking with preview app I believe they used full white for text in dark mode. That's like the most basic beginner designer thing. Don't ever use full white/black for text.

So of course I have issues in dark mode especially at night and need to use light mode then.

Is there a way how I can change the color to a lesser white so my eyes won't get problems and I can continue using the dark mode?
