The blue color of the fabric is often used as a chroma key, which means it can be easily replaced with a different background or image using digital editing techniques. This is often used in special effects and post-production work, allowing actors to be filmed in front of a blue screen and then later placed into a different environment or setting in the final footage. Molton is a heavy-duty, fire-retardant fabric that is often used in stage and event production due to its durability and ability to block out light and sound.
