By using the color stop positions gradients can be designed to be very short transitions, or “hard transitions”, to create new styling options.
As example, this full slide PowerPoint rectangle is created with 10 color stops* going from very dark blue to blue with long/smooth transition and a white hotspot (vertical line) created by positioning the color stops very close to the white creating “hard transitions.”
* TIP: the maximum number of color stops PowerPoint supports is 10.
