Pixel art involves creating raster images that can be edited pixel by pixel, often found in 2D video games and on mobile devices. Concept art does not need to be realistic, and the approach is chosen by the artist to best convey the intended style. Textures are used to make game characters and objects appear more realistic. Background graphics, also called themes, are images displayed on monitors. Print media art involves transferring ink from a matrix or screen to paper to create prints.
