None of the colours featured in your two pics

I totally agree with you. GO NEUTRAL. Add colour thru access. I used Hog Bristle. Honestly, book a Colour Consultant thru Dulux or who ever, who will come out and give u the best advise. Dulux Consultant charge about $150, but this is refunded off the paint you purchase. So ur getting expert advise for nothing, if u purchase the paint. Money well spent. I did this and was so glad I did. She will explain where to use what paint, being 1/4, 1/2 or full strength of the chosen colour. I was going to upload photos for you of my rooms, but for some reason this page won't let me. If you would like me to send you photos thru email, I would gladly do so. ir u send ur email address. Good luck.

We do need a photo. What colour is the roof?

there are some interesting putty grey colours in the knots of your floorboards. I reckon it would be worth holding some paint swatches up to the boards and see if you can find one that ties in with those driftwood tones in the timber . Then order a sample pot in a half or quarter strength version of the matching colour then see how it looks. Otherwise it is so hard to go with colours people have named, as every space has different light. If you are happy with the colour of the floor boards, let them guide your choice and you can't fail (as long as not too dark). :)
