Chroma Key Blue 3M x 3M Cotton Muslin Backdrop

Chroma key blue screens are typically used as an alternative to green screens because some find them easier to colour correct. Furthermore, blue screens have less colour spill compared to green screens. When you watch green screen videos, you might notice a green tinge on the edges of the subject, even if the background is totally different - that is called 'colour spill'. However, blue screens require more lighting because they have a lower luminance value so it doesn't reflect as much light as a green colour would. This makes blue screens good for darker scenes or darker environments.
