Works of art that express a cold/distant tone might depict characters that are emotionally disconnected, with little or no interaction between them. Beyond representation, art elements such as muted colors, minimal rendering of form, hard edges, outlines, and/or somewhat indifferent paint application might contribute to a cool/cold tone.
An artist might impart a cool/distant tone to a piece due to his or her own detachment, or the artist might choose to evoke this tone as a reflection of the character(s) or scene being portrayed. A cool/distant tone might also be adopted to suit a piece that will be shown in a setting that demands an expression of aloofness.
