My daughter has SW Light French Gray in her room and I love it. It is a medium tone, but very neutral. One thing I would suggest along with painting samples in the room would be to hold some of the accessories you plan to use up next to the sample. I once painted a powder room a nice silvery gray, only to have it turn purple when I put lavender accessories in the room. Everyone who came over commented on my purple bathroom. It didn’t look awful, but definitely wasn’t what I was going for.
