check the Colorbond Websites for some combination with Wallaby and Surfmist and congratulations on doing the painting before installation and make sure you paint all four sides for best protection

Hi Hamish, these planters are very cool! Great potential here. - from what I can see; your home has brown and red tones, it depends on the look you are trying to achieve - however if you were aiming to integrate these planters into the existing colour pallet I would go for something with orange, brown, or red undertones - I know orange sounds frightening! Bare in mind that colours look very different when under direct sunlight, or dark shadows cast by trees etc.. Before painting it's always wise to do a test on a piece of thick paper or cardboard; see how it looks in morning light, afternoon sun, dim light at dusk, and so on... What is the light like at your place? If your home doesn't get much sun I would go for a lighter colour (lighter greys with brown undertones) to bounce off the sunlight that does reach it. A darker colour (browns, oranges) would add impact, a focal point, and would boast the greenery, as the natural colours from your plants would be intensified against a darker backdrop. I have outlined some colours that would look well balanced with the rest of your exterior - Good luck! - I look forward to seeing an update

Look at Monument instead. Wallaby looks ok but I don't think it works so well with your brick.

Did you think about using some colour , or maybe even timber , instead of grey and light grey and off-grey and greyish cream ? Hamptons ( apart from being a different building style ) is crisp white , high quality accessories and maybe a stronger grey or blue . If I wanted to get anywhere near a hamptons feel ( not even technically correct for Hamptons 'style' ) I'd go option 3 , BUT with a stronger roof vent , the door column in a high quality schist or similar stone , multiple paned windows , a cedar garage door ( or maybe crisp white with mid blue surround , but you'd have to carry the mid blue through to the front door and probably gutters and even highlights on an otherwise crisp white front fence ) . I know thats blunt , but there are whole suburbs that are variations of your design and colours , and they aren't in the Hamptons ( unless the Hamptons is a suburb of Newcastle or Adelaide ) .
