GIMP YCC Inversion
August 19, 2008 - 19:05 — Stratadrake
Performs a value-inversion on the current layer, based on its representation in the YCC colorspace. The result is similar to the existing "Value Invert" command (but without that command's color-distortion introduced from low RGB values) and can be quite striking on certain source images.

Run it twice
This is not a criticism, but just an observation that if you run this filter again on its own input you do not wind up with the same image you started with. There are some subtle differences. So it can't be doing a true value invert. Some sort of artifacts or distortion is being introduced.
