Going to be redecorating our Victorian sitting room soon - dark blue for the walls would go with the curtains and sofas, and the room has a big bay window with lots of light, and high ceilings, so it could probably take a dark colour. A friend did her sitting room dark blue with mustard accents and it looks really nice. However, am not sure if dark blue is going to look terribly dated in a couple of years and we will regret it. I don't want to redecorate in years to come before absolutely necessary!
Photo isn't my house but shows the sort of colour we're considering. Also we'd white above the picture rail and on the ceiling, like this photo.
Opinions welcome!
