Tip
Like most things in Illustrator, there is more than one method for saving a gradient
swatch. You can also save a gradient by selecting an object with a gradient fill or
stroke, clicking the Fill box or Stroke box in the Swatches panel (whichever the
gradient is applied to), and then clicking the New Swatch button ( ) at the bottom of
the Swatches panel.
Click the X at the top of the Gradient panel to close it.
With the jellyfish shape still selected, click the Fill color in the Properties panel. With the
Swatches option ( ) selected, double-click the “New Gradient Swatch 1” thumbnail to open
the Swatch Options dialog box.
