Houzz is the new way to design your home.
the wood siding is western red cedar with a clear coat. the rest is stucco with Benjamin Moore painted finish. to be honest the color choice eludes me, but color is very dependent on the light involved. i would recommend picking several greys and putting a swatch up to consider what works best.
Example palette: Get a similar look with (clockwise from top left, all from Mythic Paint): Gold Beach 086-5, Ports of Fancy 136-6 and Castle Rock 134-3.
