What colour to paint hallway?

[Confusedhousehunter]

It's a 1930s house with stained glass front door that I'm going to paint teal.
The living room is blue and the downstairs flooring is quick step old white dark oak.
I can't decide whether to paint it Dulux Timeless or something like F&B elephants breath?
It could be quite a dark hallway as the only light source is the front door and little side window next to it.

Does anybody have any great suggestions?

I have just painted my living room Dulux Dusted Cappuccino which is very similar to Elephant's breath. It looks very good but the living room is South facing so light, the same paint didn't look so good in my north facing bedroom. But it is a warm grey brown so may be worth a tester.

My hall after much deliberation will be Dulux Polished Pebble, which is a lighter grey. It sounds quite similar to your hall in that it's a dark, large 1930's.
