"sh" is probably "/usr/bin/sh" ("$ command -v sh" or the (now-deprecated?)
"which sh" will show you which "sh" is being called), which is probably a
symlink to "dash" ("ls -lah <path>" will show that to you).
But not necessarily.
Perhaps one of the easiest ways to get color in a bash/dash/sh shell is to
use ANSI Terminal Escape Sequences. Not 100% portable, but probably
suitable for what you want.
Something like:
#!/bin/env sh
printf "\033[31m"
printf "Now we're printing in Red\n"
printf "\033[0m"
printf "Now we're printing in the system default color.\n"
