two games as a guesser gave me a breather. Time to cash that in.
User58 guesses with Avi on her side, so it's time for a stern debriefing.
I'm going second.
Blue words: Shadow, Concert, Fork, Bow, Strike, Egypt, Worm, Sub
Black: Kiwi. Shouldn't cause trouble.
Concert looks like the oddball here, so pair it with Bow? Issue, Organ is red. Solution, Organs aren't used in a symphonic orchestra, being too big to fit through the door. Maybe add Strike using percussion. Opera is yellow. Theater is red, so also a problem.
