Why are green screens green?
In: Technology
You can make them any color. Blue used to be the most popular color (and still is, when green can’t be used), and yellow has also bee used in the past.
The thing is, the technology that they use for this isn’t smart enough to tell the screen apart from anything in front of it. What effects softwarw *really* does is take out everything of a particular color, which you usually set to be the color of the screen. But if anything in front of the screen is the same color, it will vanish too.
Sometimes you *want* that to happen. For example, if you’re working with puppets, you can dress the puppeteers in full-body suits the same color as the screen. Then the puppeteers will be cut out along with the background, and the puppet will look like it’s moving on its own. But if I stand in front of a blue screen wearing a blue shirt and jeans, then moat of my body will vanish and I’ll look like a floating head. That’s usually *not* what you want.
So most of the time, they pick an ugly eye-bleeding color that nobody wears, like that bright green. That way, there’a not much risk of the screen taking out things it shouldn’t. And *if* it still does, you can find another color.
