YCgCo: general preparation.
I stumbled upon something - the green orange transform :-)
No, it is not lossless as some publications say. Instead, like traditional
YCbCr it maps the RGB color cube to a pyramid with a central symmetric
hexagonal base. Roughly 80% of color depth gets lost this way. The green
resolution is again worse than ITU-R 709.
It will probably not replace traditional YCbCr. It is incompatible with
existing video equipment, and it lacks an mpeg range mode needed for live editing.
However, if you can live without video equalizer, it makes an interesting
alternative for slow devices like smartphones.
Anyway, just if someone likes...
