I know the prevailing wisdom is dark grey or black, to make the foliage stand out, but currently the fence is dark brown and the overall effect is extremely gloomy. The fence is north facing and low down (sloped garden) so while the bed in front of it does get sun morning and evening, the fence itself is shaded, damp and woodlandsy.
I was wondering about a kind of mushroom colour - any thoughts on whether this would work? For what it's worth, the house itself is white.
