Blue Screen
A blue screen is a special type of background used in film. It's a bright blue color that helps animators add different images and characters to a scene. When they're done, the blue color can be easily removed or replaced with another background. This makes it easier for animators to create cool and exciting animations!

Blue screen, also known as Chroma Keying or Green Screen (and sometimes other clours), is a technique commonly used in stop-motion animation and filmmaking to create scenes that would normally be impossible or too expensive to shoot in real life. The technique involves replacing a specific color (usually blue or green) in the background with a different image or footage. This allows animators and filmmakers to composite different layers of animation and create special effects.
In animation, blue screen is often used when animating characters that need to interact with real-life objects or people. By filming the scene with a blue screen background, animators can easily select and remove the background and replace it with a different background. This process requires careful planning and attention to detail to ensure that the final product looks seamless and realistic.
## Why Blue Screen?
The blue colour is used because it is not a common colour in nature, making it easier to remove from the background. It also contrasts well with most other colours, making it easier to replace with a different background. The different colours are selected based upon the scene being filmed and the colours it contains. If the characters or environment uses a lot of blue then a green screen may be used instead.
How is Blue Screen Used in Animation?
One example of blue screen being used in animation is in the popular children’s show Sesame Street. The show uses blue screen technology to create scenes where the human actors interact with animated characters such as Elmo or Cookie Monster. By using blue screen, the show’s producers are able to seamlessly blend live action footage with animated characters, creating a magical world for children.
Another example of blue screen being used in animation is in the 2009 film Avatar. The film used a combination of live-action footage and computer-generated imagery (CGI) to create its lush alien world of Pandora. To achieve this, the filmmakers used blue screen technology extensively throughout production. By filming actors against a blue screen, they were able to replace the background with CGI environments that perfectly matched the performance.
Using blue screen in animation requires both technical and creative skills. Animators must plan their shots and lighting carefully to ensure that the characters match the background that will be inserted.
