night modus - colour of fonts

Good morning and have a nice St. Nicholas Day.

The following problem in the day/night mode of the automatically adapting theme at night:
The background is dark and the font color is black.

How can I set it so that the font color is white on a black background in dark mode and black on a white background in light mode?
Best regards

The following problem in the day/night mode of the automatically adapting theme at night.

Is this on your Mac where it’s automatically changing to day and night mode ?

If it is, I disabled that in the OS and then just set fixed dark or light theme in eM Client.

Thank you but this in no solution. I don’t wanna change my system just to get the day/night funktion ready. Can anybody explain to me how to change the colout of text at the nicht mode of eMClient from black to white?
