I'm told that there are loads of shades of grey. Blue grey, warm grey, green-grey. We have them all in our house. No actual colours though.
warm grey

OK, is it just me that actually likes white uPVC windows then?
A few years ago a house in our village was having new windows fitted and they were white but the trims that hold the glass units in were blue and they looked fantastic! The next week when I went past they were all white, the blue had been a protective film that they removed.
We have white windows.
Nothing wrong with greys you just need to add colour in other ways (furnishing/flooring/art etc)
I dislike 'greige' when everything is that colour tone, just looks like a posh hotel room.
better than all white or magnolia though.
Grey was one of two color choices we had when our house was built. All the interior walls and the ceilings are grey. I hope to paint them another color soon.

They missed a trick with the car here though.

painting cars the same colour as the tarmac seems a sensible thing to do 😆
