Hi, This is Mostly Explained/ Discussed here, though the Original Video File that is Referenced here, has been lost to time (As far as i remember it was some kind of Surfing-Type Telephoto Shot with a lot of very small, very colorful looking Water Droplets Moving all around the Frame in front and around the Surfer in a Very Harshly backlit Scene):

If that Discussion doesnt quite Answer your Question, let me know, could post a bunch more Links to even More Detailed Explainations.
In Short, use DNG as a Save Format on your Camera and if that still doesnt Work well enough, look into using Different Debayering Processes in Editing.

#EDIT#:
Forgot to say, but also make sure, that your Camera Firmware is up to date!
