I would say that a nice bright colour would go with the walls. E.g. Purple, dark blue, red

No worries, Emma. I envy anyone who can picture an outcome from a 5x4cm colour swatch. I can’t. I need a bigger, more realistic visual clue. We’ve been through the same mind changes with selections too, including whether to render or not. We were fearful of creating lifelong work, fixing potential cracks in the render and repainting. In the end, we decided to leave it alone, and have an unassuming (or even deceptive) street look that makes everyone go ‘wow’ when they walk through the door because inside is not what they expected from the outside. We’ll see how the house dates in the years to come and re-visit the idea of rendering at that time. But like you, my main prob is the colour of the window frames. I’ve spray painted some internal frames. They look heaps better. Just gotta get motivated to do some more!

I would be looking at the problems in the design of your elevation. Nice colours aren't going to fix it. Your house looks older than 1980's, and looks like it has good bones. Your entry porch looks quite wrong and you there will be other options for the WIR window if you get a designer who can think outside the box. I would suggest that you get some 3D modelling done so you fully understand the proposal as it looks like an expensive extension that could be better resolved. Best of luck with your design, Dr Retro of Dr Retro House Calls and Dr Retro Virtual Visits

I don't think it overly matters , but personally I like the darker frames for the contrast -- lighter frames are a bit whimpy .
