FWIW, I use a light background as that is easier for me to read.

Might I suggest that instead of fueling a bikeshed war about what terminal
background should be used, read what the background is of the console and
adapt the foreground colours to that. I would guess that means holding two
sets of the eight colours and if the background is "dark", use the lighter
set and if the background is "light", use the darker set. Then the
variable is superfluous.

Make it usable for everyone rather than just a subset of users based on
personal preference.

Kudos for that.
