I like @kelly's idea of picking a lovely fresh color of paint for the door. You can then bring it down onto the stair risers. Either a solid color to match the front door, or go wild and add some decorative elements to the risers with stencils. Or think of staining the door a great color and coordinate the stair railings and risers. I have an idea book put together for just such project that might spark some ideas for you. http://www.houzz.com/ideabooks/16700983/thumbs/Kathryn-Delany-s-Decorative-Stair-Risers

Is this picture taken during the day or at night? If it’s daytime your kitchen must not get much natural light. Go for white cabinets to reflect as much light as possible to brighten the room up. Boring but timeless & always looks fresh. For colour you could do a splash back, or just add colour via accessories such as a bright kettle/toaster set, tea towels etc., easier & cheaper to change if you get tired of it.

Personally , I think the main colour is fine , the crisp white on the poles and most of the terrace is fine -- the two different 'sandy khahki' shades ( the window surrounds , and the planter ) looks out of date . I'd do both of them in charcoal , as well as the terrace base board and the upstairs downpipes . It looks like the barge board and the veranda are already a charcoal -- if not , then darken them up too . The mid grey on the steps etc is fine as is , it's hard to see in the photos but the front door looks like it might be a nice solid wooden one -- again , thats fine to me , but I'd do the door surround in a crisp white to make it more noticeable . The other brighter option would be to do the window surrounds , the door surround , the top barge board including the gables , the terrace base and probably the terrace top rail -- all in a bright sunshine yellow !

Wanting to paint the exterior of our house, located on the Northern Beaches in NSW. Unable to change the window frames that are a bronze aluminium, not my choice but need to live with it. Suggestions of paint colours that would co-ordinate well with the bronze would be greatly appreciated. Current house pic (included in post).
