I love your outside entertaining area. It does need a color that would complement but give the area a focal point. I like the darker red,orange colors you may find in natural. You could dress up the table with accessories and place cushions in a complimentary color on the benches. Colored potting containers would also bring it all together. I like the uplighting here in the photo you could place along the back fence to add drama. Your area reminds me of Modern mediterranean landscaping.

Photos would help us a lot but mint and grey usually goes well with charred oak.

Without knowing any more info , I'd say its near impossible for anyone but you to know what colour/s to choose -- do you want the house to blend in but have its own style , or do you want it to stand out ? What colours are your main furniture items and even kitchen etc ? For xxample , if keeping the beige walls , how about doing the eves and gutters and garage door in a tangy ( bright , but not glaring ) orange -- this would work with the existing colours and not require a complete repaint . BUT if your kitchen was mainly various shades of , say , green and teal , and your lounge suite and duvet covers were mainly blue hues , that may 'feel' funny , clashing with the exterior ? Of course , blue and beige exterior may not work with the brown aluminium , as youve recognised . Another option ( a bit hard to tell from the pictures ) is that a light grey ( repaint the beige ) with mid-charcoal base boards may work with the brown aluminium , then a bright colour on the gutters and front and rear doors to suit -- anything from sea blue to bright yellow , orange , red , even white or off-white would probably work .

I am blown away from down under by the help that you all have freely given .... thank you sooo much indeed. who would have thought after a year of anguish that I would be put out of my misery! If I do go for the atlantic for chairs I will bring in plum touches and vice versa. Will now need to go and find some plum that closely aligns with your suggestions. Thanks for saying we can keep table! It is a good solid NZ made oak one ... chairs were all the rage back about 18 years ago! Now need to go! I will put up a pic of a rug that was quite nice but rather expensive so ... might be in an hour or so. Thank you so much again.
