A 'Trace of Color Image' typically refers to a visual art piece that focuses on a subtle or minimal use of color. This could be a painting, photograph, or digital image that emphasizes the delicate interplay of hues and tones without overpowering the viewer. Such images often convey a sense of simplicity, elegance, and depth. They can be found in various artistic movements, including abstract expressionism, minimalist art, and conceptual photography.
