Would you consider painting those two yellow feature walls a dark grey? Charcoal grey but not black. The rooms seem to have a lot of light so I think it could work, it would be a neutral that goes with existing furnishings but without being a boring beige.

With the roof tile colour I suggested off white, but NEVER WHITE as you'd need sunglasses to enter (talk to a roof painting company). It's also a way to minimize heat by reflection, therefore lowering cooling cost and making life more comfortable, plus very aesthetically appealing. Though the down side is more regular semi pressure cleaning. I do like mid to light grey for outside timber decking or tiles under a roof line with this colour combination. For anything else as far as outside in direct sunshine, stay light but in the same hues, it can be too hot to walk on barefooted if remotely mid to dark in colour.

Can you take out one of the garden beds (front left) and do a smaller deck area to transition from the upper deck down to the paving. I think you need a much lighter colour to provide light and contrast with all the tropical plants. Agree yellow and orange are not helping create a relaxing outdoor area. You already have warm colours in the terracotta tile around the pool so a colour for the walls that cools them down, look for neutral tones in lighter blue/greys to reflect the pool. You can see the difference in the photo above which looks much lighter than in your photo with the dark brick and terracotta orange on the walls which just seems to suck the light out. Large pots can be in your favourite pops of colour to great interest and contrast. Good luck with your project.

Hi Jenna, Have a look at Colorbond Evening Haze instead of Dune. If you go to a Masters store you can pick up The Wattyl Exterior Colour Solagard Brochure. When you open it up on one side of the colour chip centre page you will see the colours Monument, Surfmist and Evening Haze - this is the "Cool" colours side the other side where Dune is placed is the "Warm" colour side. When choosing colours try to stay with cool or warm tones to create a harmonious look.
