I agree with Dimitris - it is all a matter of preference - not all eyes are the same. For myself, I find the default dark theme in Pharo very uncomfortable. On my system, some elements have a black foreground on a dark grey background, which is almost impossible to see. This is always true of the maximise/minimise/close buttons, but sometimes also of text fields in a playground. Whenever I download a new image, I immediately switch to the Watery theme, with light background and nice coloured buttons on the windows.

Of course, my eyes may not be typical. I am now aged 84, and I have had cataract operations on both eyes. My sight is actually quite good - my optometrist confirms that I am legal to drive without spectacles - but my adverse reaction to dark mode is strong and immediate.

Just my 2p worth

The research is pretty clear: a large majority of developers does better with light themes. I have been sufficiently clear on the choice to make
Pharo6 theme dark default
