+A **color gradient**, also called a color ramp or color shift is a [[sequence]] of colors which gradually shift from one color into another color by changing one or more properties of the initial color.
+Primary properties can be value, saturation and hue or simply the red, green and blue components.
+In the examples shown here, the changes are given as functions "delta p0 (i)" where p is the changed property and i is the index of the color in the sequence, i=0 referring to the initial color. The function values give the change relative to the initial value of the property (p0).
+Changing only the lightness is closely related to the concept of [[tint|tints]] and [[shade|shades]].
