Life as a Designer. Grey color in interior design.
You may not think so, but gray is a very useful color, especially as an additive to other more intense shades. This is particularly true in decorating. Try mixing your own paint colors and you will inevitably, in the end, have to add a little gray, simply in order to render the color softer and more lively. This simulates adding some of a color's complementary, a time-honored artist's technique for livening up a color so that it appears less synthetic.
