Neutral colors are colors that are not too bright or too dark, and are often used in interior design. The term 'neutral colors' can refer to three specific colors: ecru (5 letters), beiges (6 letters), and TANS (4 letters). Ecru is a light brown color, beiges are a range of light to medium browns, and TANS are a range of yellowish-browns. These colors are often used to create a calming atmosphere in a room.
