We don't do a lot of redecorating, but I tend to stick to soft yet warm, earthy colours. When we built our home I wanted to keep everything, including the colour scheme, as natural as possible, so we used organic, clay-based paints in various shades of honey-beige and cream and teamed that with natural bamboo flooring and ocean blue.
I think following trends, whether in fashion or home décor, is a big mistake, as by doing so we compromise our own individuality and self-expression. Popular trends also go out of fashion very quickly, which can be expensive in a big investment like home décor.
