I actually meant this in jest, which is why it has the smiley face
afterwords.

I don't know which is more popular, light or dark themes, I'm glad that
Pharo makes it easy to automatically change to which ever one prefers -
which was what the code following this sentence was demonstrating.

I had my terminals set to black background with green fonts up to last
year since that is what I was used to from my Dick Smith System 80
(TRS-80 clone). :-)

Going slightly off topic: I suspect terminals used a dark theme by
default because a light theme would burn out the CRT.  If I remember
correctly, DEC VT-220's had a light theme (which I didn't use).

I largely agree with what you've said.  My eyes have just deteriorated
in the opposite direction - I can't read with a dark theme (my terminals
are now dark text on a white background).

My apologies for any offence, it wasn't intended.


Cheers,
