I'm trying to modernise my home. Getting contemporary fittings and furniture. I have a black leather couch, some pine timber furniture, a white kitchen... So I'm really stuck of a good colour wooden flooring. I'm not a huge fan of my terracotta look tiles but it's simply to expensive to replace them all.

I would paint the walls white as primrose looks great with this. Paint the pantry door trim white to match the door and see how you like that, cheers

Id opt for a predominantly light neutral colour for the rug, in a large size, so the area looks lighter and more spacious. A rug with a basic stripe pattern could also help make the room visually look bigger - placed so that at the entry point of the room the stripes run vertically to make the room look longer. You also cant go past mirrors for giving the illusion of a larger room so I would suggest a couple of decent sized mirrors, or a single large mirror, on the mustard colour wall - it will also reflect light back into the room making it a brighter space.

The sample in the pics does look a bit yellow. I’d stay well away from anything with a red or yellow tone. I love your ceiling and it’s a feature to try and keep but as it is domineering you need to be careful of your other choices. Is the sample board a pre-finished board? On one hand that’s good because you can see the final colour but on the other hand it’s bad because the final colour is lot quite right.
