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 .

The roof will be a dark grey/charcoal colour. The gutters are an off white colour, windows are white and we have cream brick all the way around. I am unsure what colour to paint it. I want to keep away from green because my house is surrounded by a sea of green. My husband thinks a light grey along with a new timber front door.

Looking to repaint our house. Love to hear any ideas for paint colour that will suit the buttercream joinery... plus the base, do I try to match the roof or do same colour as whole house....

Have you tried the Dulux Visualizer. I have used this personally and found it to be quite helpful. It allows you to take a photo of your home and then experiment with different colours to see what works best. Another option you might consider is the Sherwin-Williams ColorSnap® Visualizer app. It allows you to upload a photo of your home and then try out different paint colours and combinations to see what looks best. I hope this helps!
