I love hardwood spotted gum floors, they add so much warmth to a space. I'm trying to visualise your space, but I'd be inclined to go for a light shade, maybe a light pebble grey to complement your walls, and add texture with a charcoal suite. Good luck!

This is the room in question the furniture will be replaced with a creamy white suite but the carpet will also go when the new furniture arrives

I've just been looking at your colours, I think the Dulux Dieskau would work the best with the other colours you have to work with, choosing colours is such a personal thing and I know it can be really hard to choose and hope you make the correct choice. Oskuee is right, a paint job can look terrible half way through so you need to make sure you finish to get the proper look of colour. But the biggest thing to remember is it's only paint and it's the cheapest thing to change so if your not happy with the colour you choose you can always try something else. Happy redecorating :)

I like the idea of hardwood flooring and as previously said you can add nice rugs for comfort and texture, they can be changed out at any time for a different look or fashion, I found light carpet shows all spills and marks and as also previously said here dark colours show lint, animal fur and anything lighter like fluff ...I do think hardwood floors in the long run keep you from having to re-do carpet especially as you have no idea how the renters will treat your investment. I also find myself having hardwood flooring with rugs it is all so easy to keep clean.
