In the paper [0] there is more info than just what's explained in the simplified blog post. A.I. is needed if you want to do the same without the color chart used for training it. Furthermore, it is not just color correction, also backscatter is taken into account.

They actually correct by using wavelength-dependent Backscatter and attenuation models while accounting for camera spectral sensitivities and illuminant spectrum. This is much more complex than "just color fixing".

The publication shows that it is not a simple colour correction: http://openaccess.thecvf.com/content_CVPR_2019/papers/Akkayn...
