Everything I've ever seen is a lie.

It's all shared imaginations. Someone imagined this and shared it with you. We are blessed!

Watch a TV series that was filmed in your home town and you'll never again even remotely believe that ANYTHING is what it says it is!

Whenever I see a scene in which the actors don't wear green (like almost ANYscene), I smell a lie. 
But that's OK. I like to be lied to if it's for art.

 do you see alota people wearing green in real life?  its not a very popular wardrobe color.  its not very popular/prominent in anything realy, except vegetation.  thats why its a popular keying color.

it has nothing to do with that.. it´s about skin tone.

Not about that either, chroma subsampling removes too much information in the blue and red, because our eyes are more sensetive to green, and since green is the color with the most colorinformation in it after subsampling, it's perfect for keying.

Actually, green is magic.

Green is just used for Chrome Keying because it is the least common color to wear. Many Chroma key backdrop canvases are green on one side and blue on the other so you can flip them around for scenes that need green.

 actually its because there is very little green in skin, so when you pull a green key there is less chance of the key getting confused and removing part of someones face.  it also just happens to be an uncommon clothing color.

Yes, from what I've heard, it's because green and blue are as far away you can go from skin tones. They didn't say "Hmm, what color is the ugliest? People will not want to wear that, so let's use it as key".

In addition to being 180 degrees out of phase with red There are actually more important reasons. Most of the luminance information is in the green channel. Since it hold most of the luminace in a video signal it is sampled at twice the rate of the Blue and Red in most professional formats. Green is uaually used in digital. In film most of the Keys ar pulled from a blue back ground since the blue layer of the emulsion holds most of the detail / resolution information 

actually we are doing as much blues screen as green screens today.
