The Gradient Swatch Tool creates a gradient! Crazy, right? It makes it over the entire object you’ve selected. Simply drag from one spot to another to adjust how intense of a gradient it is. The longer the line, the more gradual the gradient becomes. The spot where you start is the one color, and the spot where you end is the other color. You can also change the colors, intensity, and direction in the Gradient Window on the right-hand side or in the Windows menu.
