Digital colourising is just confirmation biasing for people who expect things to look a certain way. If we drew a big Venn diagram showing:
1) People who are good at colouring in photographs in Adobe Photoshop
2) People who actively enjoy colouring in photographs in Adobe Photoshop
3) People who's knowledge base is sufficient to allow them to identify what colours stuff was in B&W photographs
... the overall overlap in the middle of the Venn diagram would be miniscule.
In almost no subject is this more of a plague than with the Royal Navy, whereby colourised photographs can give the impression of being very well done, yet if you are one of the relative few who has access to something with far more gravitas then you're suddenly the only one out there knowing that it's wrong.
It's a bit like being offered 2 weeks of waterboarding in Guantanamo Bay for free - it sounds brilliant, provided you don't know what either of those two things are!
For some American ships it's perhaps harder to screw them up if they're just 5-N and 20-B everywhere.
Still most people viewing these either a) presume the person with the digital crayons must have known what they were doing (which is patently false in most cases) or b) presume their own common sense a robust enough quality check (similar to how people who know nothing about cars think a nice "think" when the doors close implies high quality engineering and therefore mechanical reliability over length of ownership)
