There may be multiple steps in the progression as well - for example, it may start by transitioning from red to yellow, from yellow to grey, and from grey to black. A familiar example of a color progression is the color range represented in a [[rainbow]]. ==Mapping== Color progressions are often utilized in [[maps]] and other visual representations of [[data]] in order to convey additional information. [[Geographic information system|GIS]] tools use color progressions to indicate [[elevation]] and [[population density]], among others. [[SimCity]], a city simulation computer game, uses a version of color progression in its geographical maps. ==Image editing and creation== Image editing tools such as [[Adobe Photoshop]] commonly refer to color progressions as "[[color gradient|gradients]]." Images of [[fractals]] are often created with a palette that utilizes smooth color progressions, which tend to emphasize the intricate detail the fractals contain. ==External links== * [http://gislounge.com/glossary/bldefmaps.shtml GIS glossary] {{color-stub}}
