Mind blown
Would love to see this effort combined with a technique to discover the correct color using multiple sources and Dr Dre’s magic autocolor technique that I wish I could have a copy of. 😉
On my own, I discovered using After Effects, when I wish to color correct something, I can get really close by adjusting the levels with individual controls as long as the histogram of each color has room on either or ideally both sides of it. I just slide the right and left slider to just before the ramp up for each individual color and that gets it close. Then if it is too green or pink or blue, I adjust the center slider a bit until it looks right. It really makes the picture punchy and much more correct in color most of the time unless they intentionally changed it from the original color. This usually needs to be done scene to scene and sometimes if it is a long scene, it needs to be tracked and changed throughout the scene.
