It depends what the colour is used for. Blue is my favourite colour for bedroom walls, and I have had mine blue for decades. For living room walls, I prefer cream, for the hall, I prefer green.
In the garden, I like as many colours as possible. In mine, I have orange, yellow, blue, pink and purple flowers, plus a lot of green from trees, grass, bushes etc. I think in a garden all colours go well together in a way that they wouldn't in the home. As far as clothes are concerned, I like every colour, except for black or grey.
