Khun Hino,
Pictures always appreciated, especially if they reflect a question that needs to be addresses to Khun. I will be commenting on some recent pictures in a follow on entry in a day or two.
The most recent posted pictures above do not reflect a real accurate comparison between the color of the paint on the exterior of the house and the perimeter wall. From your view, what were you able to determine?
As it relates to the interior/exterior "earth" color scheme, I will have to say that Mrs SEA and myself agreed pretty much on having neutral colors and nothing too ostentious. A little highlight was desired and I think we accomplished that with the trim around the windows and the dark brown colored soffit. Mrs SEA was left with the responsibility to actually pick out the colors though and after she selected them and presented the colors to me. On one of the colors, I asked a question or two about, she eventually changed it but overall, she did the matching of the colors. With the eventural adding of medium cherry wood color of the Makha wood floors and the Teak doors, the dark chocolate brown soffit and front gate, along with the darker trim paint around the windows, I think that she hit a winner. But, to each their own. We got what we were looking for and are pleased with what we selected...
One thing I will add though, Khun's scetch artest and interior designer for the built in custom kitchen/bathroom cabinets and other special amenities was top notch. She did provide some real good ideas. I'd suggest you talk to Khun about possibly talking to her or including her in your design process.
Again, thanks for the insight and looking forward to some of Neung's pics being forwarded. Possibly they will show a better compairson of the colors than the cell phone pics.
