May I suggest a cap of your pavers on the wall and the a slightly darker gray that relates to the privacy fence beyond? That way horizontal surfaces and vertical surfaces show similarities and blends/blurs the separations?

Small all in one condo room not sure what color to use for walls after removing wallpaper

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 .

Looking at the bench , I assume that aged look is what you are going for ? How artistic are you ? I'm thinking you'd carry on in a similar vein -- paint the trim in white , but while its still damp ( so within say 30 minutes ) dab on some off-white and even buttery cream , using a sponge , in a bit of a 'rub' pattern . Likewise , I quite like the faded blue jeans look on the sill -- thats a bit harder to do , but maybe a cream base , then thin the blue with turps or water , and also sponge it on , but basically in solid rubs , like you were nuggetting your shoes .
