Thanks Jonathan. I’m not totally adverse to the yellow and perhaps your right less yellowish window might help crisp up. I like the warmth statement and blending with greenery that current colour has but it needs painting badly and so having moved in last year feel need to make a change and loose yellow. I suppose as it is tired and everything in the house is either yellow or green (avocado) and tired!!! I’ll look at greys with off white windows as you suggest......

I need the dark yellow colour equivalent in ncs colour charts

My kitchen is painted a duck egg blue too. I have cream units, oak worktops and a white ceramic sink. I agree with colourhappy to get the kitchen fitted, fit the worktop and sink then look at painting the walls, although your wall colour is soft and will probably go well. I’d go for a white worktop, with veining if you want some pattern, then go for a white sink. Black just wouldn’t go with the soft colours and they never look clean, especially if you have hard water. Although I love my duck egg walls I’m going to paint them F&B Oval Room Blue, which is a darker version. Just fancy a change! This is a corner of my kitchen.

It depends on what else you have in the room, the sofa colours etc. It looks to be a really nice room with some lovely features. Personally, I wouldn't paint it all a blue or a dark colour as East facing rooms can be gloomy on an afternoon. Have a look on instagram, there is a total shift away from dark interiors towards more neutral warmer ones. Not that this matters, but perhaps a year of lockdown has made a difference to what people want to live with.
