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.

I Like the up down cylinder/square black lights but your lights are high set so it would be just down light. I have a light like the last photo but it's a chunky cylinder instead of square, I think I got it at Bunnings ages ago, it's on an internal courtyard wall and looks amazing when turned on. Could your cousin do one of each, ie: up down and just down, Just down on the entrance as you don't want to light up the entrance ceiling and up down on the tall wall, it would be great if it could be dropped down a bit. cheers

Thanks Bigreader, I really love the Australian bush greens and greys and the palette you posted above. The cream on the windows is so yellowy though. Do you think this will clash with the colours you’ve suggested?

rereading your post i now realise that the windows are already grey but would be great to have the gutters painted to cover the green but instead of hand painting check with the local powder coating company as it's possible to have the gutters powder coated ..we took our gutters down and had to put them back up again...tedious but more effective than hand painting
