Blue screens can function exactly like green screens but are less common. This is for a pretty simple reason: Green is a color that shows up less often in scenes. However, if you have a lot of green in a scene, like plants, trees, and other foliage, you’ll want to introduce blue screening, as it will make the editing and post-production a lot easier to manage. The contrast between your screen and the objects you are filming in front of it is essential for adding video effects.
