It's the computer trying to copy the color from the training image set onto the video. My point about a guy in a bright red or hot pink suit in the B&W original being represented as sepia/navy in the colorization is still the same. It's impossible to turn B&W image into a color image without guessing what the colors are. The average color of a guy's suit in the colorized copy might be right if it's trained on a realistic dataset, but ultimately it's still guessing and making up information for each individual suit.
