I love working with neutral tones, also known as monotone. The use of a single neutral color describes a monotone scheme. Colors such as light grays, creams, beiges, off-whites, light browns and silver leaf, are all classic colors with an understated look.
Neutrals are quite, and are regarded as safe and non-offensive, sleek, clean and classic.
