After adding gradient fills to shapes you may want to make some changes to the gradient fill. Or, you may want to change the colors comprising your gradient outlines. To do so, you must be familiar with gradient stops. A gradient stop is the point where a new color is introduced within the gradient blend. Unlike PowerPoint versions on Windows, PowerPoint 2011 for Mac does not really use the term “gradient stop” – in fact no term is used and probably, this version just refers to these stops as ‘colors’. However, we will call them stops within this tutorial.
