Gradual transition color images refer to a visual technique where colors change smoothly from one to another, creating a seamless transition effect. This technique is commonly used in graphic design, photography, and video production to create visual interest and convey a sense of movement or change. In graphic design, it can be used to create backgrounds or to animate elements. In photography, it might be used to blend images or to create a dreamy, ethereal effect. In video production, it can be part of the editing process to create a smooth transition between scenes.
