Thanks Anne and I will look at pale grey given the maintenance considerations. I have already paid for a colour consultant who was great but the Reckless grey she suggested for the house render and basalt gutters/fascia and front wall were too grey when we had the render samples put on and while it had a modern look, it was not giving the beach/coastal feel. I will head back into our inspirations paint store this morning to see if I can find the warm grey colours that have the most similar colour make up to Dune, and go from there. Anne you don't happen to know the dulux colour most close in composition to Colorbond Dune so I know where to start? Thanks again and I would love to hear from anyone who has got a dune roof and hear if they tried light coloured gutters and what render colours they have used on their walls.

Thanks for your response annb, and comments on the house. Took me a long time to choose door colours and very happy I went with a dark colour rather than white for the doors to contrast the white walls. Your correct, it's Spanish/Mediterranean style, and really appreciate your thoughts.

You can use two approaches depending on what look you are going for (the images aren't the exact shades) 1. Darker contrast. For this I would recommend Taubmans "Mojo" or Dulux "colorbond monument". The dulux shade is more grey to the Taubmans navy. 2.Alternatively you can go lighter: I would recommend Dulux "Lexicon" (either half or quarter) or Dulux "Vivid White". The difference in aesthetic is shown below (ignore the clapboard, its just an easy reference point to show aesthetic).

some photos would explain the dilemma
