Yup. The man, nroff, groff, grotty and more man pages are all
relevant.
man uses nroff, which is a shell script that invokes groff with one of
the character output drivers, which then uses grotty to produce that
actual output. That is piped through more, which recognizes the the
hardcopy underline & control sequences, and turns them into the bold
and underline sequences for your terminal.
I think you have three choices:
1) Change your terminal type to one that uses the colors you want
for bold and underline, which are the only ones used. This will
change the behavior of all programs that use those terminal
features.
2) Change your PAGER variable to something that recognizes those
hardcopy sequences and changes them to the codes that you want,
then passes that to "more -rs". Note that this will change the
behavior of all programs that use the PAGER variable to page
through text.
3) Create a new groff device (ansi?) that does what you want.
You can probably start with grotty. Disable the saving of
formatted man pages, and change the /usr/bin/nroff script to
use this driver if you're on the proper device.
