This is because the Chroma buttons work by identifying the green and blue colors in the background and replacing them with other backgrounds. Although all colors can be used, green / blue is the preferred color because it is the skin color. Since the colors blue and green are unique and do not conflict with other colors on your skin, you can use them in a variety of different situations, such as on a computer screen.
The origin of Green Screen
Originally, the blue screen was used by the film industry for chrome keyboards and special effects. Green Screen became widely known because it is easier to work with them in post-production. Sometimes you use chroma key backgrounds in the film to remove colors. When removing colors during chrome wedge or post-production, or to superimpose a motif on another background in a scene.
There are a lot of things to consider when deciding what colored Chroma background you want to use. Here are just a few basic considerations to follow when deciding which one to go with.
What to wear in front of a Green screen?
If you are filming in front of a green screen and want to be invisible, you should wear the color green. Check out this video for some green screen tips. Visit WeVideo Academy to use the Chroma Key tool like a pro. There are a lot of great resources to get started with green screens, and plenty of tips on how to film with them.
Wearing the same hue as the background will lead to the color to be entered, but not vice versa.
Although this may seem obvious how many people forget to be green when they shoot on a green screen. If for some reason it is necessary for the green to have a company logo that is green, then the solution is to use a blue screen instead of a red one, as you may have recognized.
What happens if the subjects wear green or partially green?
Of course, one has to make sure that the test persons have no or at least not too much blue in their eyes.
After all, green is a rarer color used in clothing. So you won’t get as many problems as with a blue screen. The color green makes it helpful that it is brighter than blue. Therefore the most obvious disadvantage of the green screen is the amount of color wear.
Removing paint stains from subjects can be difficult in post-production. So the Chroma button consists of removing the video from the background and re-coloring it.
The Chroma button is also called color separation and is generally referred to as Green Screen or Blue Screen. When it comes to green screens and blue screens, both screens can be used in the same way by using the “Chroma Key” technology to place a subject in front of the projected background.
The foreground motif has a lower chance of wearing green clothing, while the background motif does not because of the color separation of the green and blue screens.
The green screen also responds better to light than the blue screen. For one thing, most digital cameras capture much more color than blue screens. Most videographers often come to the same conclusion when it comes to which color to use for the Chroma buttons.
The green screen requires less light than the blue screen. The green reflects more light because it has a brighter luminance. For this reason, green channels are also used for lighting, which in turn leads to a higher luminance for greens in post-production.
When the chromate keyboard was first used in television production, the blue screen, which was the norm in the film industry at the time, was used due to other practical considerations that led to the television industry moving from blue to green screens. Green was also used as a backdrop for television and electronic cinematography, because television weathermen tended to wear blue suits. It is also a brighter green, causing fewer problems in the post, but it is also more expensive than the green screen due to its higher luminance.
Early analog TV chroma keys required the RGB component of the video to work.
Which one is better?
From a technological point of view, it was equally possible to use both blue and green channels. The basic idea was to film subjects in front of a uniform blue or green screen. Since blue clothing was a constant challenge, green screens were used, and while digital compositing is commonplace. Nowadays, the idea of filming subjects in front of blue or green screens has long been an integral part of special effects.
