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.

I look at the first picture , and the most noticeable thing ( in a good way ) is the letterbox -- its an offwhite by the looks of it . So I'd do all the trim in that , and it even works with the roof ( sort of ) . The garage door is okay as it is -- the lighter tones elsewhere will balance that IMO . Ideally , I'd look at changing the garage door to a cedar timber at some stage -- again that would work with the roof , bricks , trim , etc . Probably just me , but I'm with you about going darker -- it may look 'dingy' , but none of them seem a fit with the roof IMO . Even something like surfmist ( off-white with a slight blue tinge ) doesn't gel in my mind . If you had the budget , and did want to look more modern , THEN maybe go a charcoal like monument , BUT with the cedar ( or cedar stained ) garage door , and 15 or so 40x40 battens , again cedar stained , basically the length of the 3 right side poles , so there's still that 2 metres or so in the middle that is 'open' . The cedar door on the left , and battens on the right , will visually look reasonably balanced and modern , without being too symetrical . The downside is it will cut down the light a bit , so depends if thats worth more than looking modern .
