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.

If you do decide upon pink - the more greyed-out, knocked-back, toned down pinks feel less sugary and can be a little less wearing on the eye than more full on PINK! But, if you have a room which feels dim, you may find you can afford to use a slightly more colourful pink than you might think, in order to show-up through the gloom. From top to bottom here the pinks become increasingly more colourful. It is possible to find a suitable pink to use in most every room : the secret is partnering the right amount of colourfulness to work with your available light.

I would class those cushions as more of a rust as opposed to orange. Could you swap them for a definite bright orange and also have curtains that have a large proportion of orange in? Walnut has undertones of orange so l think it would work well together.
