I would echo what Susie said. how about a nice tan or med to light grey? I have many times spun my wheels to try to pick out a thread color...only to realize it could not be seen anyway! I am not very matchy matchy with my colors either. I found if I matched colors to a fabric, then on THAT fabric you cannot see it, and on the other fabrics it stands out. I have a good tan (Permacore Mother Goose) , a lighter grey (gray opal or pearl opal...something opal! also Permacore) and Omni spearmint (a nice soft green). Those are my go to colors.
