You may notice that your local meteorologist bucks the trend and doesn't wear green on St. Patrick's Day - despite the fact that this can lead to pesky pinches through the day. If you pay careful attention, you'll notice that meteorologists never seem to wear green throughout the year. There's a good reason for that and it's all about the work environment.
Meteorologists do their weather presentations on the news in front of a chroma key screen. Here's a picture of what our chroma key wall looks like here at the Newsplex:
That's right, it's just a wall that we painted green. However, this wall works in combination with our studio cameras to produce the graphics that you see every night on the news. The studio camera takes anything that is green and turns it into a weather map, with the meteorologist having to use the monitors on the side to see where to point. Since the camera takes anything that is green and makes it a weather map, that includes clothing of the meteorologist. If I wore a green shirt, a green tie, or green suit jacket (not that I would ever do that), they would all be transformed into weather maps.
So there you have it. The science behind why your TV meteorologist will never be caught in green. Now don't forget that on Thursday! Any questions, feel free to post them!
