Thank you to all for the wonderful feedback. I didn't intend to paint the walls blue rather a taupe/brown - the De Sousa home is a great example. Since publishing the photo and the question - I have viewed many fabrics in many shades of blue and came to the conclusion blue is probably not the right choice. The photo looks beautiful but have moved to silver/grey with plum purple walls. But keeping the padded bedhead with demi lune side tables, an occasional chair in far corner and I already have the perfect bedside crystal tired lamp bases already. Again, could go very wrong with purple but I think I've found the perfect colour here in Australia. There are some stunning fabrics available in the silver/grey tone and I think it would well in the bedroom. The starting point funnily enough in moving to silver/grey was stumbling across the most gorgeous drape fabric. Then I built the rest from there. Now it's down to making final selections. A frustrating but fun process. Can't wait to see end result. Fingers crossed it all works out! Thank you once again - this site is amazing and your feedback is most helpful.

Pick the cappuccino to have a contrast with the windows...it will be much more soothing than a stark white.

Thanks @mcmahonandnerlich for your considered response! Yours is about the only positive feedback I've had for Vivid White!! I love the cleanness of the test areas we've done but am a bit nervous that we might find it too clinical. Also a bit concerned our bedroom may dazzle our socks off as it will get afternoon sun in winter! Can you allay my fears?! And are you at all familiar with Snowy Mountains Quarter? It has a smidge of black and ochre in it, so is a tad warmer but not as warm as Natural White. Finally, do I need to be worried about the impact of our charcoal polished concrete and charcoal carpet on the final paint choice? If the paint has any black in it will the dark floors bring it out in the paint? Sorry to bombard you but your comments were so apt ... Thanks in advance!

What a lovely house, a paint update will look really exciting! Contrary to all the colours you've chosen, I'd go instead with a warm grey (hint of taupe in it). It will always be classic, would look amazing with fresh white window frames and dark charcoal eaves (e.g. Dulux Monument). Cue my favourite colour: Dulux Dieskau. I just think there's quite a large area of uninterrupted rendered wall so I'd worry that if you go too bluish, it could look to be verging on pastel and a gingerbread house type effect. My brother painted Tranquil Retreat on his rendered Victorian and it has come up more blue than he'd thought (actually he was also considering Milton Moon). But of course, test paint a few walls sections with different aspects and check during the day from different angles (and even across the road)!! Actually there's another photo and paint colour I love that reminded me of this, I'll try and track it down.
