For values in the range 0 to 1, powers larger than 1 push them down and powers smaller than 1 pull them up. So, we are pushing the red+blues down and pulling the greens up a little. Images are pixels, pixels are colors, colors are numbers. And, you can do maths on numbers.

Am I reading it right in that red and blue look like increasing, and green is decreasing? I would expect it to get more magenta rather than green

It still bugs me they did that to the digital/HD versions. I loved the original colors from the theatrical release. But I do admire the mathematical simplicity.

I can make a filter out of this. 🤔

we could apply this transform to Matrix 4

Similar to gamma correction. Eye perception is not linear. Plus these non linear formulas do not overflow the color ranges.

wow that's amazing, do you mean they literally used the above formula or its an approximation by you to do the same color effect ?

Would you say this The Matrix's identity?

I'd say its the inverse of that.
