It is a nice time to play with the real colors around us. Just a levels correction and you got it.
When we see the video in our camera's LCD, it has a lot of color and nice contrast, but when you move it to the computer, you get pale, grayed and muddy stuff. the solution is very simple. Cut a 10% in the darks, and a 5% in the lights using the color curves, and the color is there. Of course each clip is different, but you can start like this. This plug in can save your day and give you other options.
