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).
