Hi, the garden faces the roadside so full sun, at current wet and windy, typical Brisbane QLD weather, the left hand side faces the driveway, the other towards the side gate

Okay, firstly, this is very difficult to do without seeing the room in person. So rather than suggesting a colour, let me tell you some theory and hopefully you can work it out. The painting looks a little yellow on my screen, I think it would look different in person. You want the image to stand out. What you're looking for is contrast between the image and your surroundings. Contrast can give seperation between elements and that's what you're after, the wall to receed behind the painting. white is not cutting it because it's competing with the image. The image has some light bright tones ie it's bright and the white wall will be bright, so a while wall and the painting will both compete for your attention. the other problem you have is all of the other elements in the room are darker and warm timber, we notice warm colours before cooler colours (ie blues) first, so it's likely all of thu sis competing against each other. So to not compete with everything else, you want something cooler but also not saturated (without a lot of colour). You want people to forget about the wall. again it's very difficult without seeing the room, so any colour I give you is not going to work. Get a few swatches from Bunnings and take them home and hold them next to the picture in the room. Narrow it down the 3 paints then get a small canvas, Bunnings is cheap, paint that with your colours and rest them on the wall with the painting. Move the canvas around the wall. Good luck. Colour is difficult but just try and get something that doesn't compete with the painting.

I really like colorbonds wallaby... they have some contrasting colours listed below... this might give a dark enough look without being too dark. however would you consider changing roof and trims first and then see how you feel about the brickwork? It might be all you need to do for an updated look. I'd maybe do roof and gutters same colour and then down pipes in a colour similar to bricks so not to stand out..., garage doors maybe the woodland grey?

are the new sliding glass doors double glazed? are the original windows single glazed or in need of replacing for any other reason? do you hate the beige colour? how many of the old windows can be seen at the same time as the new doors? ... inside looking out is the most important view for me but what do you like the look of?
