Depending on the tint and shade of blue, it can represent different feelings, thoughts, and emotions. In imagery, dark shades of blue can give a sense of sadness. An expression that goes along with this is “singing the blues” when someone is sad. Light blue is the color of the sky and of water, which can be refreshing, free, and calm. Blue skies are calming and tranquil. Water washes away dirt and cleans wounds. Blue can represent freshness and renewal, such as when rain washes away dirt and dust. The calmness of blue promotes relaxation.
