Dark roofs absorb far too much heat; suggest midtone eg basalt or wallaby with ironstone fascias. Check out the Basix?? Heat absorption of colorbond colours

Instead of Dulux Natural White, look at a softer white with a tinge of grey which is Rottnest Island then team it with an anodised aluminium window. For the timber posts on the upstairs balcony, you may like to have them in a warmer timber such as cedar or cyprus. Go for Colorbond Monument for the gutters and fascia to give a crisp contrast. Good luck with the project!

grey and white always look good but Google "choosing colour schemes" for all the different paint companies services for matching colour schemes

Hi there, we are building a double storey similar in style to pic one. Currently looking for 2 render colours within a preference towards neutrals (earthy greys preferred). Our bricks are blackheath and roof is monument however struggling to find 2 suitable render colours. We have tried Whisper Grey and Shale Grey however Shale looks baby blue outside. Quite like Dune however would love some suggestions. Also like the colours in pic 2 if anyone knows what these might be.
