Using accurate Color samples obtained from the local paint shop, I've created a Python script to create a color filter that can be turned into a LUT tool to correct colors in video recordings. While not ideal for a final processed video/photo, it gets the footage to a standardized point that can be corrected with other LUTs that cannot be dyamically generated. This tool can create custom luts on demand; you just need the color reference card to start.

This tool can be run on Google Colab, so no Python setup or local operation is needed -- all in the cloud if desired. Check it out at the link above!
A video walk-thru of this tool can be found here: https://www.youtube.com/watch?v=pu9IpbfckDo
OBS Studio comes with several LUTS, including the neutral one we've used in this repo, as displayed below.
I created a version that's setup for the Datacolor SpyderCheckr color card:

The original source for the above neutral LUT used by this repo was found within the OBS Studio's GitHub, Linked Here. OBS Studio uses a GPLv2 licence, which allows for commercial and private use, including distribution and modification. Please see their licence for specifics if intending to use their LUT.
You are free to make derivations and distributions of my Python code, for commericial or private purposes, as allowed by the GPLv3 open-source licence. I went with GPLv3 for my own code, which should be compatible with the licence OBS uses for its neutral LUT. If distributing this code, modified or otherwise, providing a link with it to a fork of my repository with any changes shown I think is sufficient, although I'm not a lawyer and this is not legal advice.
