'''Color progressions''' are ranges of [[color]] whose values transition smoothly through a [[hue]], [[saturation (color theory)|saturation]], [[luminance]], or any combination of the three. 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.
