Description
pytest currently uses pygments' TerminalFormatter. While reviewing a PR I've noticed that pygments also has Terminal256Formatter and TerminalTrueColorFormatter which presumably have richer colors than TerminalFormatter. Maybe if we use them we'll get better syntax highlighting.
pygments cmdline tool seems to use the following logic for selecting a formatter:
if os.environ.get('COLORTERM','') in ('truecolor', '24bit'):
fmter = TerminalTrueColorFormatter(**parsed_opts)
elif '256' in os.environ.get('TERM', ''):
fmter = Terminal256Formatter(**parsed_opts)
else:
fmter = TerminalFormatter(**parsed_opts)

Research direction
Start by locating pytest's use of Pygments' TerminalFormatter and compare it with the formatter-selection logic shown from the Pygments command-line tool. Done means terminal syntax highlighting selects an appropriate richer formatter for true-color or 256-color environments while retaining the fallback behavior.
