There’s nothing “new” about black or white being neutral. Either color can be used alone or together with any other color. That’s what makes them considered neutral colors.
People who prefer this most neutral of all shades are carefully neutral about life.
You prefer a secure, safe, balanced existence, and so unlike the reds in life, you never crave real excitement, just contentment. It is important for you to maintain the status quo.
You are practical and calm and do not like to attract attention. You are willing to work and to be of service. You are the middle-of-the-road type, cool, conservative, composed and reliable.
