I once saw a gorgeous grey house with a chartreuse door and lots of purple plants in the front of the house. Wouldn't work my (horrible) salmon pink house (one day it will be painted) but since you have the grey might be worth considering?

I think the roof might be a bit too dark for the brick colour. The bricks and the window joinery will blend in fine. What did you decide to do?

As hatetoshop suggests, paint the front doors in both entryways. Here are examples of some blue doors that look good with tan siding. Agree that it's worth enclosing your garbage cans somehow in your other entrance. Replace your entry light fixture with something modern along the lines of the light shown below. Find a nice large indoor/outdoor rug mats that coordinate with the painted doors--tan and blue for both entryways. Try Overstock.com Get some big pots in the door color and coordinating colors and line the entryway fence with some tall plants suitable for your climate to break up the wall of white. Can't tell if you've got any soil in front of the wall where you could put in some plants instead. Inside your fence, clean up the yard then plan some landscaping. So that you have something nice to look at from your kitchen, hang some plants in colorful containers from the fence. If you really want to get fancy, paint some simple wooden window boxes in the blue door color, hang them across the kitchen window, and fill them with herbs and/or flowers if you get enough sun. Or do the same with large planters below your kitchen windows. Put a small colorful bistro table and chairs back there.

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 .
