Rather than hijack Gaross' provocative thread, here is a basic color correction test for video editors.
This is called a "ringaround" in the photo industry. It is used as a cc reference, to calibrate optical printers, and I also used it to screen new employees at Pallas back in the day ;?)
In the spirit of a visual exercise, no eyedroppers, samples, or masks, please. You are not to judge the color of the reference (it's your monitor, remember?). The choices are C<M<Y<R<G<B in random order, starting at the lower left and going clockwise. There are no "tricks" (i.e., combination colors have been left out). Notice how flesh tones (mostly red and yellow) don't always behave the way we expect to color shifts. A few experienced graders will get it right away. Most won't. That's why we need a reference.
