I'm not sure if this does what you want, but I threw it together in
the hopes that it was close. Just visually highlight the range
(linewise, characterwise, or blockwise) that you want to highlight
and press <f4>. Adjust the "Error" at the bottom for whatever
highlighting group you want (in the case of your example, "Green")
