The concept of wearing green on a green screen is related to the field of chroma key compositing, which is a visual effects technique for layering two images or video streams together. In this technique, a green screen is used as a background, and the subject is filmed in front of the green screen. The green color is then replaced with a desired background image or video.
The green color is selected as the background color due to its distinctiveness from skin tones and its abundance in nature. The goal of using a green screen is to achieve a clean and accurate key, or the process of isolating the subject from the background. This requires the subject to wear clothing that does not match the green screen color.
Wearing green clothing on a green screen can result in color spill, which is when the green color from the clothing bleeds into the subject, creating a halo effect. This makes it difficult to achieve a clean key, and the final composite will have a noticeable green edge around the subject. This is why it is recommended to avoid wearing green clothing when filming in front of a green screen.
In conclusion, while it is technically possible to wear green clothing on a green screen, it is not recommended as it can result in color spill and make it difficult to achieve a clean key. The best practice is to wear clothing that does not match the green screen color to ensure a successful chroma key composite.
