color correction 

Can be very simple, but it can also be incredibly detailed and intricate. Think about what we have done so far: we have looked at the waveform monitor and made sure that the blacks were at 0% (video black) and we kept all of the detail in the shadows. Additionally, we have worked with the highlights-making sure that they are close to 100% while also making sure they have detail as well. 

Let's start with basic color theory:

To the left is subtractive color mixing and is usually associated with print. The reason why it is called subtractive is it creates black when all cyan, magenta, and yellow are mixed equally (in paint or ink.) Additive color is associated with projection, videographic, and photographic images and creates white when all of the colors are combined.

More practically, the color wheel above is very helpful to understanding how all of the correction below works. If you have an image or a part of an image that is too green, blue, or magenta you add the opposite color to neutralize it. For example: if an entire image is too blue, you will add orange to take away the color cast.
