In mathematics, the

**gradient**is a multi-variable generalization of the derivative. The**gradient**is a vector-valued function, as opposed to a derivative, which is scalar-valued. Like the derivative, the**gradient**represents the**slope**of the tangent of the graph of the function.Likewise, people ask, how do you change a gradient color in Illustrator?

To

**change**the**color**of the**gradient**, select one of its**Color**Stops in the**Gradient**panel, then choose the**color**model in the**Colors**Panel and then set the desired**color**. If you work in Adobe**Illustrator**CS4 – CS6, then by double clicking on the**Color**Stop, it opens**Colors**or Swatches panel right in the**Gradient**panel.What is the gradient stop?

Use

**gradient**fills to apply a graduated blend of colors as you would apply any other color.**Gradient**colors in Illustrator are defined by a series of**stops**along the**gradient**slider. A**stop**marks the point at which a**gradient**changes from one color to the next, and is identified by a square below the**gradient**slider.What is a radial gradient?

A

**radial gradient**is defined by a center point, an ending shape, and two or more color-stop points. To create a smooth**gradient**, the**radial**-**gradient**() function draws a series of concentric shapes radiating out from the center to the ending shape (and potentially beyond).
