Advice on F & B French or Blue Gray please

[TheHouseofMirth]

I want to paint our very big and south facing bedroom grey but can't seem to find the right shade. So many greys seem to look very lilac and I'd like one with a hint of green. Looking at swatches doesn't seem to help and Googling "grey greens" has thrown up these two. Seems unlikely a paint called Blue Gray would been greeny but apparently it is.

Any advice on these or any other shades to try (doesn't matter if it's not F&B) would be gratefully received. I have bought enough testers to paint a battle ship and it's all getting ather expensive!

Have blue gray in our hallway and it is very green, much more green than i expected and definately much more green than grey but absolutely beautiful.Different lights bring different effects too, which alters the green/grey balance.Get lots of compliments about the colour, and although I thought I wanted a more grey grey,wouldn't change it at all.

Shaded white f and b is a nice grey.
