which skin colour is a question here as well. There are a lot of variations and I'm not sure that a black and white film is going to contain enough information for you to know. There's a danger of white-washing (or the reverse!) history by mistake.

I think the point is that you simply don’t know in a lot of these videos. They’re random bystanders, not known figures with photographic evidence. So you’re not going to know what to recolour it to, or if it’s even wrong in the first place.

Not all shades of skins are the same within one specific demographic.
Unless there's also a way to accurately extract the specific hue, you will never get anything accurate.
Anyone that ever wore foundation can tell you that human skin has tones, undertones, different reflective qualities, etc.
Just look at https://www.temptalia.com/wp-content/uploads/2018/05/summer-... or https://cdn.shopify.com/s/files/1/0009/0000/5932/files/Shade... or this https://pbs.twimg.com/media/B_zp3U1XAAAk4Iz?format=jpg&name=...
So if you were to recolor a film you can take skin colors from today. But an advert, car color or fabric is incredibly difficult, even if you have the original, since the material will have degraded. Even if you repaint it with the original paint it will look different, since the paint will have changed, or if you use new paint the process to manufacture the paint (->led).
It might as well be another universe.
