Flexibility is offered by the COLORFGBG variable. The entire time we've 
been talking only about cases where that is not set.

Again, it is good to reduce to a minimum reliance on defaults. But aside 
from having a default the remaining option is to refuse to produce 
colors when COLORFGBG is not set, even when the user is explicitly 
asking for colors.

/etc/profile.d is shell session configuration.

If you want you can come up with shell magic that would set environment 
variables depending on which terminal environment the shell is running in.
