F&B Railings - does anyone have it on the walls? Or Floors? What is it like?

[SuePerb]

I am redecorating my entire house. I currently have white painted floors and cornforth/ammonite throughout. (It's nice!). But really like Railings - initially for the floor boards, but now possibly the walls instead. Do you have it? what does it look like? What other shades do you have?

Can you share please?

Watching with interest as I'm thinking of using it on one wall in the dining room. It's a lovely shade and not as harsh as black.

It is a lovely colour.

Yes I've seen that picture too - love the fireplace and wall. (I think the wall is Downpipe - can you tell I've spent too much time on pinterest?!).
