Changing the Arduino IDE tab color
The text inside the tabs of the Arduino IDE is hard to read because the background color is dark blue-green. You can change the color to enhance the visibility:
To change the color, replace these files in the folder C:\Program Files (x86)\Arduino\lib\theme\ with these files, which you can download at GitHub:
All instances of blue-green #4db7bb have been replaced by yellow #ebef0b . You should do this again if you install a new version of Arduino. Who can help to further improve the color scheme?
Changing the Arduino comment font color
Comments in the Arduino editor are hard to read because the color is light grey, I wonder why this color is still being used. This color can't be changed as usual in the preference.txt file, but has to be set in the theme.txt file, which can be found at this location:
C:\Program Files (x86)\Arduino\lib\theme\
You can download the changed theme.txt file at GitHub here.
As an example, the comment font colors are changed to blue here:
# TEXT - COMMENTS
#editor.comment1.style = #434F54,plain -> #0920ed,plain
#editor.comment2.style = #95a5a6,plain -> #0920ed,plain
