Balboa mist by BM. No hint of blue, just beautiful.

First, there is no such thing as a perfect gray because gray paint can take on different undertones depending on factors such as lighting and room size. That said, Sherwin Williams Passive Gray worked great in my open space living areas. It's a cool light gray with no blue undertones.

Thank you both I have painted my basement den repose grey Sherwin Williams after flooring went down I feel like it looks like a light baby blue ! What do y'all think ??
All the same room last two are before the flooring went down

I'm not seeing the blue from the picture but it could be the lighting and the quality of the picture, so it's hard for me to tell. I had a hard time picking the right gray so I ended up trying about 15 different samples (Sherwin Williams sells little containers of samples for $5 each). You probably don't have to try as many as I did but it could be a good investment to buy about 4-5 samples. You should put the different samples in different areas of the wall and wait to see how it looks during the day with sunlight and at night with artificial lighting.
