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

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.
