Hi, I like the overall concept of the darkish grey, it suits the home. I am a colour consultant and have been working with the Dulux range for 17 years and you are on the right track with the Guild Grey. The Dulux Signature will give you a dark blue house. Another option if Simone Weil which is just a bit lighter than the Guild Grey, if you find that one too dark. Sample pots and A4 brush outs onto white cardboard are the best way to decide, because computer programs give an overall impression of the "look" but are not accurate with colour choices, you can't beat the human eye. All the best, it's going to look great.

1. Paint over bricks, either in a light grey (white-wash) colour or a mid grey/blue-grey... https://www.houzz.com.au/photos/resort-inspiration-tropical-exterior-perth-phvw-vp~4028776 or https://www.houzz.com.au/photos/bilgola-house-contemporary-exterior-sydney-phvw-vp~12387394 2. Paint the cladding/paneling on the side in a colour opposite to the one chosen in 1. above... https://www.houzz.com.au/photos/decarle-st-oak-park-contemporary-exterior-melbourne-phvw-vp~6535555 or https://www.houzz.com.au/photos/marbel-st-contemporary-patio-melbourne-phvw-vp~1520623 3. Reseal the roof tiles in a darker grey-blue or bluestone/slate colour, similar to this, but match the garage door colour to the roof colour (i.e. not that timber look) https://www.houzz.com.au/photos/ethel-st-oak-park-contemporary-exterior-melbourne-phvw-vp~6535879

You can get any colour paint you like in any strength - 1/4, 1/2, 3/4 or full - its only a colour, so they will mix it to your request. Have you made yourselves a colour board? if not, you will need to get all your selection colours together and then go to bunnings or a paint shop and get some sample pots of the colours you are debating. (yes it will cost to get sample pots, but seriously you need to do it - and get the varying strengths in the same colour as well). If you are worried about the render colour marking, go the 1/2 strength on the render and 1/4 on the mouldings. Your Wow factor will come with your varying textures - brickwork/render and trims/timber doors, and the wrought iron. I'm guessing you have exterior lighting? some beautiful exterior lights will be the icing on the cake.

From your latest photos it looks really great, glass would look awesome also , it really depends on the look you are after, glass would look really modern but that iron work looks really great, decisions , decisions.
