Thanks guys for all your input. I am loving that Emily Henderson room and that contemporary/mid modern century room! I am after a light and bright space and I do love the greige trend - just not sure how I can do this considering all the beige tile and cabinetry in the kitchen. Can I transition from cool undetone to warm in an adjoining room?

Perhaps keep the color as natural as possible to compliment the greenery outside.

I know this is an old post but just in case anyone is still looking for Sherwin Williams Sea Salt paint...... When Wattyle were still owned by Sherwin Williams, a couple of years ago now??, I asked the Head Office of Wattyl if they could help me get some Sea Salt in Australia. I'm in Sydney and they advised I needed to find one of their stores with a Hydrochroma machine(not all of them have one) to have Sea Salt made up due to the type of tint used in the paint. They also provided the tint mix. I went to Wattyl in Brookvale and they made me up 4 litres of Sea Salt paint. It's a great colour but looks pretty bland in the tin. I don't know whether the Wattyl white base changes how it looks either. Anyway, anyone wanting Sea Salt can have it made up at the Brookvale store because they have the name and tint mix in their computer. Now they aren't owned by Sherwin Williams I don't know if they can access any other of their colours as they don't have access to their database anymore.

If you re considering Colorbond colours, Shale Grey is a good light colour. Or, a darker grey is Windspray.
