Think the Thunderbolt might blend out as more purple. Dark for slats is good

I would paint the roof charcoal grey, the exterior walls a lighter grey. Trimmings in black, same with the slats beneath the verandah. It would blend into the environment and bring attention to the view of the mountains in the background. To add a pop of colour and bring focus to the front door in an inviting way, I would paint it red.

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.

@dreamer yes I was thinking a simple timber balustrade would look better than a more modern one. we are planing on putting a covered deck off the back with a similar balustrade too. @fianou Luca I love fixed upper. They were the reason we bought this house as I could see the potential. it is much harder than it looks go bring a look all together. I was contemplating painting the brick lighter like a wash but to scared to vomit incase it looks terrible and it is an expensive job to do. I was even thinking of putting shutters on the windows downstairs to give the front some texture
