Anyone used Farrow and Ball Light Gray ?

[DixonOfDockGreen]

I am trying to get a colour that will match in with an existing pair of curtains.
Farrow and Ball Light Gray looks like it might do, but it also looks like a fairly dark colour which if used might make the room feel a bit dark. Has anyone used it before ? The room is a medium sized living room in a 1930's semi which faces south - east.

Anyone ?

can you tell me if you went for this colour in the end? surprisingly few images of this colour available when i search ... i'm wondering why! i am all set to decorate my sitting room with it so hoping you had success!

I have used farrow and ball light grey outside. It is not really light grey it is similar to Laura Ashley light truffle.
