Other than a limited causal appreciation of 'colorizing', i'm definitely not really a fan for the most simple reason that it's not the actual true and correct colors, hues or shades etc put in by an AI software algorithm. It is CGI-approximation for the senses ... For instance, Take a number of color photos - remove all color, run it though a AI algorithm - the hues and shades are noticeably different but it is true that it has now being 'colorized'.
