Why does IA still struggle with colorization of old movies.

There's a ton of data for training neural networks. We can just use modern movies, decolorize them and use them for training.
It's maybe the field with the biggest data for training neural networks.

I checked 2 years, how do colorized movies look I was disappointed, then I checked again now after the last 2 years revolution of generative IA still disappointed

Most of movie colorized by IA have bland colors. It looks more like a monochromatic movies: blue and …
