Hi,

I was thinking you could go for a colour called Great White from Farrow and Ball which is white but in the different lights throughout the day it has a really soft warm colour to it.You could check it on the Farrow and Ball website. Another thought would be to go in the opposite direction and go for a darker colour. It might sound that it will make the room darker and smaller but you would be surprised that it can have the opposite effect depending on your lighting. There is a paint colour from a company called Little Green.The colour is called Juniper Ash. I will attach a photo sample of it. It is a really beautiful colour. Then with either of these colours the flooring could be a natural fibre say Sisal or similar in a soft grey. There are lots of companies out there that are very reasonable as they used to be super expensive.But prices have really come down.

Grey would also work well on the walls but err on the darker rather than too light and you could then get a few grey cushions with different patterns on them. For a more modern feel mixed with blues and maybe some white to tie into the fireplace.

Another possibility is a dark moss soft green.

You could put a throw of some sort over one side of the sofa back which would soften the terracotta block of colour.

Indoor plants have come back into fashion and also have health benefit. The green of the leaves would also complement the colour of the sofa.

Good luck with it all. Contact me if you need anymore help.
