This term originates from the technical process of chroma keying, where a specific high-contrast color is isolated and removed. While blue screens are also common in the industry, green is more frequently used in modern digital production because digital cameras are more sensitive to green and it provides a sharper contrast against human skin tones.
As a verb, the term is a functional conversion from the noun, describing the act of filming with this technology. It carries a connotation of artificiality or cost-saving, often used in discussions about visual effects (VFX) and the balance between practical sets and digital environments.
