If you’re someplace where trees and grass will be visible in your shot, you’re better off using a blue screen. If there’s a large body of water in the scene, then green is the way to go. Because blue screens have lower luminance, there’s less chance of color spill around the edges of your actors.
Why did green screen replace blue screen?
Because green clothing is less common than blue, it soon became apparent that it was easier to use a green matte screen than it was to constantly police the clothing choices of on-air talent.

What is the blue screen used for?
A blue screen is a monochromatic background for filmmaking, television, and video production projects. Chroma key compositing, a visual effects (VFX) process, utilizes the blue color to isolate part of the image. This process allows editors to switch the color out for a new image in post-production.
Is blue screen more expensive than green screen?
This is because the green channel is also used for luminance, which, in turn, makes green easier to key out in post-production. Green screens also require less light than blue screens because green reflects more light — again, because it has a brighter luminance. Requiring less light means it’s cheaper to use.

Why is green screen best?
The best green screens do far more than offering just a colored background to superimpose your surroundings, though. High-quality materials will absorb your lighting better, protect against wrinkles, and some are even machine washable which helps to maintain cleanliness and avoid dirt and dust build-ups too.
