The dark purple area of the gradient needs to be bigger or more spread out. To do that, you can
adjust the spread of the color.
Move the pointer over the Dark purple color stop at the bottom of the shape. When you see the
dotted circle appear, drag the widget at the bottom of the circle away from the color stop. The
dark purple color will appear to “spread” further away from the color stop.
Click in the shape to add a new color stop (see the figure for the position). Double-click the
new color stop you just added, and change the color to the Pink swatch.
