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.

@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

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.

This may be of interest....https://www.houzz.com.au/discussions/4984679/new-house-colour-advice-needed-please . I went through many sample pots for my previous house before getting a colour consultant to help me. However, I have colour consultants from Dulux to be a bit hit and miss and some always just choosing the popular scheme that is seen everywhere. I know one of Dulux' brochures had a house in miller mood...maybe see what they teamed it with. I found the colour pots to be very much the same as the colours shown in the link I gave...Good luck!...... To me tranquil retreat is a very safe bet that will match with everything.. If you want something more unique, than go for miller mood...
