I used this command in the terminal to find information about color and the terminal-
ulti:~$ dircolors -p
# Configuration file for dircolors, a utility to help you set the
# LS_COLORS environment variable used by GNU ls with the --color option.

Maybe this database is stored in the binary executable of the dircolors command itself, but it can always be overridden by settings in /etc/DIR_COLORS or better by $HOME/.dir_colors (for your own personal settings)
If that doesn't work than the only other thing I can think of is to look up
on the top bar of the terminal; pick Edit and pick the default profile and edit it. Pick the colors tab
and check or un-check
(depending on what you want) the box for "use colors from system theme"
Hope that helps
