A plugin that I found recently is called “Temperature,” created by Creative Impatience. I thought that the tool looked like it might be interesting, but I didn’t have any plans on using it very much. I have been extremely surprised at just how useful this tool is for colour correction. Here is an example of one of the shots from the trailer, which was greatly simplified due to this tool.

I added on the effect onto the Lego Storm layer and turned the temperature to -1. Here is the result:
This usually would have taken multiple effects and still would not have ended up looking this good. I highly recommend this plugin.
