I'm not familiar with these colors but try and keep them similar i.e. A blue grey, a green grey, yellow grey etc. that might help a little bit when thinking about your choice. Also I would do the same colour as you use on the render, (bricks) on the weatherboard above the garage or if you aren't keen on that, make it lighter. I would not go darker up higher. I would however do a very dark fence, assume the concrete one on the left. The other option, as it looks like you are embarking on quite a large project, is to change the existing colours i.e. garage door. I would choose a colour for the garage door which matches with the main house colour. Go with your gut! Good luck.

I can't quite follow what you mean by 'we must keep the red roof' ? Are you not painting it , or repainting in the same colour , or would you consider a different shade ? Personally , with the White Duck , I'd go for a bolder red roof , with black or charoal gutterings , stay with the crisp white windows and veranda uprights , and the end detailing on the roof , but the window sills I'd do the same red shade as the roof , and the deck a mid grey . Oh , and also , although its cliche'd , I'd do a 1 metre tall white picket fence and double gates in the crisp white , get rid of the wire mesh haha , so everything about the house and fence looks crisp and themed , but also 'period' .

As I suspected it is not yellow, but already an earthy colour. The windows frames, roof trims, front door and frames would all look good in one of the sample colours given. They all definitely need maintenance and painting. Adding a stained timber porch deck and squared off timber support posts. The back balcony balustrade could be either painted or replaced with a stained timber balustrade. I would ask a painter as to their thoughts as to whether the render needs painting again, or is it in good condition. But if you have the budget to paint the whole house, then go for it.

I think your idea of going all white would look fabulous, even your retaining wall at the front, add lush landscaping, gorgeous planters, it will look great against the white and give that beach look you are after, check out 3 Birds renovations for inspiration
