Last Saturday, I decided to wear a new shirt to work. It wasn't until I went to practice the weather forecast, and stepped in front of the green screen, that I realized it wasn't the best shirt for TV. You see, the shirt I wore was definitely the color green. Not just any green, the exact same kelly green as the green screen. As I stepped in front of the camera, I no longer had on a green shirt but was wearing the national radar instead. --Now you see me, now you don't.
Mike Nelson calls it a little a bit of TV magic. Everywhere the camera sees green, it replaces the color with the weather graphic instead. In this case, that meant my entire green shirt.
The technical name for the green screen is "chromakey", and it can come in different colors, like red, blue or green. Red is not a good choice because skin tones have a lot of red in them. Also, women tend to wear lipstick in shades of red. Blue is not the best choice either because it's a common color for clothing. That makes green the best color to use for the screen. I remember Mike telling me once that they chose that color because nobody would wear that shade of green. Oops, I guess I did. Don't call the fashion police on me. :)
The moral of the story is that I should not wear green to work!
