Perhaps keep the color as natural as possible to compliment the greenery outside.

Colour is a whole-of-house thing ie it begins at your letterbox and ends at the back fence! When I work with clients I assess their personal colour type and make recommendations from there. Often people will add just one colour eg red, as an accent and use it throughout the home...red pots at the front door, splashback, cushions, throw rug on the bed etc. Personally I prefer to use two colours to spice up a neutral scheme. They may be complementary eg red/green or analogous eg green and blue. The trick is alternating which is the more used colour in different rooms. Taubmans have a formula of 60/30/10 - the bright, intense accent colours should not make up more than 10% of your scheme. Never go 50/50 it always looks out of whack. Pick two colours that you both like, and find pictures on houzz as well as Pinterest for ideas.

Hello Of course it depends on the 'mood' you wish to create in your living spaces Colour is returning to home decorating now to add interest to neutral spaces I wonder if you would be brave enough to try a beautiful pastel turquoise to your spaces??? Like this I especially like the last one as it has grey in it

If you want a light render and you’re looking at Surfmist for the garage door then use Surfmist for the whole thing. You don’t want more than three colours inc your bricks and monument so that gives you one other colour for everything else.
