I know this is old,  but I also have a wallaby roof and looking for guidance on the exterior walls.

I was trying to achieve a white house with black trims and grey roof. I'm unsure how it's going to look now as the wallaby roof seems to throw brown in my eyes.

Gutters nightsky 

Windows matt black 

Fascias surfmist

What colour for the exterior walls?

First time builder located rural qld

Very grateful for any input, thanks

Apologies for the weird spacing - my phone

Have your finalised any part of your choices yet?

Yes they are all finalised...

All finalised except for exterior wall colour that is

That’s a lot of colours in the one house. I’d try a sample of Surfmist on the walls and see if it’s white enough for you. I’d def try to not add any more colours or tones.

Thank you BR I'll definitely try Surfmist for the walls. 

Thinking a darker or truer grey with nightsky gutters and fascias would have looked better. Hindsight is a wonderful thing as they say ;) thanks again

I had a colour consultant come out and help. Taking into account leafy surrounds and colour of homes next door, this was the outcome - it came together really well:

All exterior walls - Resene Double Truffle

Roof, Gutters / Gargae door - Colorbond Wallaby

Front door - Resene Ironsand

Window & Frames - Colorbond Surfmist

Fascia - Colorbond Surfmist

We have a lot of red soil where we live so couldn't possibly go with a white exterior or I'd be forever cleaning the stain off lower walls.

Good luck with it!

Thank you @janemacdougall ! That sounds lovely! Would you have any pics you could share? I would love to see! Understand if you prefer not to of course :)
