Herein is the reason that there are so many posts about gray. Grays are difficult. They are a long-lasting trend that has caused too many people to want gray everything. Grays often do not work due to their likelihood to have so many undertones. Personally I would quickly choose a different neutral and put the grays to rest.

Platinum Plate by Cloverdale paints is a lovely true light gray with no other tones in it. I just used it all over my main floor with a recent remodel and I cant be happier!!

We used light french gray by sherwin williams and love it. I have yet to pick up any blue tones in it. Hope that helps.
