A pixel artist is a graphic designer who specializes in computer art and can refer to a number of artistic and professional disciplines which focus on visual communication and presentation. Similar to chromoluminarism used in the pointillism style of painting, in which small distinct points of primary colors create the impression of a wide selection of secondary and intermediate colors, a pixel artist works with pixels, the smallest piece of information in an image. The technique relies on the perceptive ability of the eye and mind of the viewer to mix the color spots into a fuller range of tones. Pixel art is often utilitarian and anonymous. Pixel design can refer to both the process (designing) by which the communication is created and the products (designs) which are generated.
