The 'ae color blinking effect' refers to a visual effect in After Effects (AE), a software used for motion graphics and video post-production. This effect involves changing the color of an element or object in a video to create a blinking or flashing visual pattern. It is often used in animation to draw attention or to convey a sense of urgency. To achieve this effect in AE, users can use expressions or keyframes to manipulate the color properties over time.
