"Fade" refers to a gradual decrease in visibility, intensity, or strength. For example, when the sun sets, its light slowly fades, creating a beautiful transition from day to night. This can also apply to colors, like when a vibrant painting loses its brightness over time due to exposure to sunlight. In music, a "fade" is a technique where the volume of a song gradually decreases until it becomes silent. This is often used at the end of a track to create a smooth and gentle conclusion. Similarly, in film, a scene can fade to black, signaling a change or the end of a moment.
