It's a dilemma because you know your stuck with it for years once it's on. We recently painted our cedar exterior. Started by agreeing on a general colour and then buying a series of sample pots. We finally decided on dulux colour bond dune. Amazing in itself as we rarely agree haa. It was a nice mix between beige and grey. We bought the 10 litre tin and went to work. After completing one wall I thought the paint was taking a while to dry as it wasn't getting as dark as the sample. My husband thought it was because of the lighting. I took a piece of wood and painted the sample which we loved and the paint from the 10 litre can together and yes they were a different shade. The hardware store had accidentally mixed the sample pot in double strength. It was all fixed up and we really love the result. So it was Dulux Colourbond Dune. I think it would be perfect with your roof colour.

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 :)

You may use a specific light in the grey on the wall were there are two windows. While the other wall with a long slim window has a wall feature design. There are numerous features to use, with the intension that it would be on the same colour contrast. As was mentioned that the blinds would be great sprayed though in a colour that will go with the walls colour and design. Need to be a balance in the colours for both walls and the blinds. You may use one wall with wallpaper feature if you prefer. I have found a site that may assist you with the design of your choice. http://colorhunter.com/; http://www.resene.com.au/wallpaper/#

Thanks for the photo's it really show's what should be painted with what, just by looking at the first photo looking towards the stairs, the painted bulk head would really bring the ceiling down and then again the second with the bulk head above the external door, wall colour is the right choice for me. cheers
