Hi, I like the overall concept of the darkish grey, it suits the home. I am a colour consultant and have been working with the Dulux range for 17 years and you are on the right track with the Guild Grey. The Dulux Signature will give you a dark blue house. Another option if Simone Weil which is just a bit lighter than the Guild Grey, if you find that one too dark. Sample pots and A4 brush outs onto white cardboard are the best way to decide, because computer programs give an overall impression of the "look" but are not accurate with colour choices, you can't beat the human eye. All the best, it's going to look great.

Not sure how deep you want to go and presume both the render and weatherboard are to be the same, you could try Dulux's "Ticking" GR20, "Signature" GR17, or "Western Myall" GR23. they will all look good with the white trim and your surfmist roof, just keep some thoughts about your external surrounding eg. pavers, concrete etc. Good luck posts some pic's if you can.

Kim, where do the rammed earth sections fit into the building, in relation to the Colorbond and rendered exterior walls? Can you post a pic of design? I envy you your use of rammed earth...our house was originally designed with a rammed earth section, but finding a builder happy to contract out that portion was an insurmountable problem, so we went with recycled brick instead.

Definitely the off-white . But can I suggest that , dependingh on budget , a couple of things that I would change , that would add even more pride in your place , and also more resale . The wooden entry and wooden garage door are great features -- add some warmth ! Why not continue and reference that by adding the same cedar stained timber to at least the 'corner' charcoal coloured piece on the upstairs window -- both sides of the window may be too much ? And if possible ( I assume it is reasonably set plan , but doesn't hurt to ask/suggest ) I'd do that larger left 1 1/2 storied 'feature' ( is it presently concrete block , or grey tiled ? ) in a red antiqued brick -- it , combined with the redder toned timber accents , will really add to the look IMO .
