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

Taubmans chilly water (more green) or misty rain (more blue). i'm sure there was a design dilemma post from a while back that gave the Aussie paint answer to this question. Hopefully someone who knows will see this and link it.

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!
