Has anyone used Farrow and Ball Pavilion Blue?

[Hollycopter]

I've got fairly large south facing room with a big window that I want to redecorate and I want something bright and airy. It's currently natural calico and together with a brown sofa and brown curtains it seems dull despite the amount of light it gets.

I'm getting rid of the sofa and curtains, thank goodness but a bit stuck on wall colour.

I'm looking at Farrow and Ball Pavilion Blue. Does anyone have it? How blue is it when it's on the whole wall? I've tried a bit on the wall not facing the window and it's a kind of grayish tone there with a hint of blue.

I was also looking at Duluxe clouded pearl 3, but I think that might be a bit grey and stark in the sunlight.

TIA

We have just painted our lounge in F&B Skylight -- I too was worried that it would look too blue - but it is stunning grey/blue which is different on each wall and at different times of the day and has real depth.

Thanks deepest!
