Neutral colors aren’t commonly found on the color wheel, this is because they are defined as hues that seem to be without color. In line with this neutral colors definition, they are also known for being universal complements.
All neutral colors are quite easy on the eyes since they don’t actually have any color. This quality of being easy to look at means that most neutral colors symbolize relaxation, tranquility, peace, or neutrality in some way.
White is most commonly associated around the world with feelings of purity, peace, fresh starts, new beginnings, potential, and cleanliness. Off-whites are considered timeless, classic, and elegantly subtle.
A rule to follow is that by mixing together three primary hues or one secondary color and its complement, you will get a neutral color. Once you have created a gray or brown you can easily alter it further.
