I need the dark yellow colour equivalent in ncs colour charts

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.

I agree with the others - go for it! It’s going to look fab! I like the dull greens more than the more foresty greens, I had a bathroom painted that colour many years ago, and I think it’s less likely to go out of fashion. It’s verging on being a dark neutral.

Siobhanmcgee90 I couldn't agree more. Half curtains belong in caravans or campervans. I was not suggesting leaving it bright white, that was a base coat to remove the current paint choice so you could a get a better idea of the space. I would live with it for a while before rushing into a colour which may not be right with your new flooring. You wouldn't want to have to repaint it more than once. Don't choose a colour before you have decided what your other accents such as side tables, lamps maybe a coffee table and bookcase or shelves are going to be. I would wait to see how the sofa looks in the room first. You are rushing into a choice under pressure and might well regret it later.
