They had one - gone now, I think - called ‘Normandy Grey’ 
Very familiar …
I painted the exterior woodwork of a pal’s house, inc front door. He gave me tins of F & B ‘Navy Blue’ -ish. I could see why the interior decor merchants and mags like House & Garden love the colours but I found that was so soft - never seemed to go off to a tough glassy finish.
That was OK on the window frames but the front door started taking scuffs and marks immediately.I’d say it’s also not a paint that the average DIY’er will get on with.
