Color is being processed strangely after uploading to YouTube After uploading to YouTube, the green in my video is being processed with a weird tint (like a sea foam green). In the image below, I'm hoping for the blueish/green color on the left, but that color only shows in Safari (and sometimes Chrome) - otherwise it's mostly showing the color incorrectly.

Even more strange is when I use Quicktime on my Mac to screen record the video when the color is displaying incorrectly on YouTube, the end result when I play it back in quicktime shows the correct color. For example, watch my YouTube video: 
                
            , then see the screen capture here: https://drive.google.com/file/d/0B7-2T7XJFKEKdklRQUpDaTdUYVU/view.

This is only happening with the green color, all the other colors are correct. I'm exporting from Final Cut Pro on a Mac, I've tried my color display on my Mac at Color LCD and Color LCD Calibrated. Any idea why the color is being processed incorrectly once it's playing in YouTube?
I see the correct color on Youtube. via Flash player on Windows 7.

Sounds like either a gamma issue with the errant players, not Youtube. Try VLC.
