I have Egyptian cotton in my hall/stairs and landing. It can change between looking grey and beige depending on the light which is something to consider. It looks very beige in my house (especially next to our other grey walls) but I've seen other people say it's grey.
It's a lovely colour but looks very different depending on the light. Sometimes it's almost pinky, other times it just looks grey. That's a good thing though, it's a great neutral colour without being just grey or neutral.
This is so helpful thanks everyone. And hearing that they’re so similar is really reassuring as means won’t be a big mistake either way They look quite different from the testers on our walls - EC looks much darker - but lots of people have said full painted walls came out different to testers which was why I came to ask you fabulous folk
