some font cant be changed

Hello,

Im a visually impaired user and my eyes prefer white text and black background. I have now tried to moddify the theme.txt file in lib on Linux Ubuntu but it would be very nice if there was a theme that is dark with white text and black background..

The issue points to lib/theme.txt in the Arduino IDE on Ubuntu; inspect that theme definition first and compare how existing colors and fonts are represented. Add a dark theme with white text on a black background, then verify that the IDE applies it consistently.
