color keying
Color keying is a visual effects technique used in film and photography where a specific color is removed or replaced with another image. This process allows filmmakers to superimpose subjects onto different backgrounds. The most common color used is green, as it is distinct from human skin tones and clothing. By isolating this color, editors can create scenes that appear seamless, such as a weather reporter standing in front of a graphic map. Color keying is widely used in movies, TV, and video games to create engaging visuals and enhance storytelling.

Color keying is a visual effects technique used in film and video production to replace a specific color in a scene with another image or video. Commonly known as "chroma keying," this method often uses a bright green or blue background. During editing, the colored background is made transparent, allowing other visuals, like special effects or different backgrounds, to show through. This technique is widely used in news broadcasting, movies, and video games to create dynamic and engaging visual experiences, enabling filmmakers to place subjects in various environments without needing to travel or build elaborate sets.
