Gradients are a blend of two or more colors that progress and merge from one to another. But knowledge of colors and its combination is essential for making a gradient. If the user does not choose the right colors and gradient style, it can mess up the entire background making it look unappealing to the user's eye. The gradients are also known as fountain fills or blends.
To create a gradient background in Powerpoint:
In Powerpoint, you can edit background slides by removing the background graphic and filling the slide background with a solid color, a color gradient, a texture, a pattern, or a picture of your choice. You make these changes by clicking on the Format Background pane. A color gradient can have from 2 to 10 gradients stops spending upon your choice. (To make a gradient color, open the gradient fill panel. After the gradient box opens, we find a color box filled with two colors. We notice at the bottom of the box; there are two squares where the distinction in color is seen. These squares are called stops. These stops allow you to fill colors in them, thus making a gradient.)
