Choosing paint colours is a very individual matter.
We're not interior designers, but there are endless resources on the internet to help you choose what you want and explore possibilities you might not have considered.
Here are links to some of the more useful ones we've seen.
We recommend Dulux, Farrow & Ball, and Crown paints. Click on the images below to go to their websites.
Dulux also have a handy (free) app you can download to an android tablet or iPad. It will show you how your room would look with different paint colours, and also suggest colour combinations. It's a bit fiddly, but certainly a nice idea.
