The theme of this gallery is night. When an artist is painting or creating a piece that takes place at night, they are faced with a situation in which they must use unique colors. Using black in night pieces could make the art too dark, or draw away from the elegance or true meaning of the piece. Colors such as a dark blue, or dark purple are sometimes used to illustrate the scene takes place at night instead of using black. When unusual color, unusual meaning not lifelike, is used in a piece of art, it allows the person viewing the piece, to interpret the mood of the night scene. It could be scary, joyous, or even a quite relaxing mood.
