Colour grading is an essential step in movie post-production, which is done in the industry by experienced artists on expensive edit hardware and software suites. This paper presents a review of the advances made to automate this process. The review looks in particular at how the state-of-the-art in optimal transport and deep learning has advanced some of the fundamental problems of colour transfer, and how far are we still from being able to automatically grade images.
