Is Hand-Drawn Really Better Than AI-Generated Colouring Books?

I'll admit I went into this expecting to write something fairly balanced. Then I spent an evening actually comparing books side by side and came away a bit more opinionated than planned.

Here's the context. Adult colouring books have exploded over the past couple of years, and a fair chunk of what's now flooding Amazon and Etsy listings is AI-generated. Not labelled as such, usually. You just have to look.

Take a building. A church, a row of shops, whatever. In a hand-drawn illustration the windows won't be identical. The artist drew the first one, then the second one slightly differently because that's just how hands work, and by the eighth window down the row there's a kind of accumulated personality to the whole thing. AI-generated versions tend to repeat a window almost identically six or seven times, then throw in one that's subtly broken - wrong number of panes, a frame that doesn't quite close. It's not obvious at a glance. It is obvious once you're sat there with a pencil for twenty minutes.

Perspective is another one. I looked at a "Highland village" book recently where the roofline on one side of the street disagreed with the chimney angles on the other side - nothing dramatic, but enough that something felt slightly wrong without me being able to say exactly why at first.

What you're actually paying for

A hand-drawn page usually represents several hours of someone's actual time. Sketching, scrapping bits that aren't working, deciding what level of detail makes a window worth colouring versus a window that should just be three lines because otherwise the page becomes exhausting rather than relaxing. That decision-making is the bit that's hard to fake.

Whether that matters to you depends entirely on what you want from the book. If you just want something to colour while watching telly, fine, it probably doesn't matter much. If you're buying it as a gift, or you specifically want to support an illustrator rather than a prompt, it matters quite a lot more.

The practical stuff

Line weight is usually the giveaway once you're actually colouring rather than just looking. Hand-drawn lines vary - thicker where two elements meet, finer for background detail, because the artist was making a judgement about where your eye should go. AI tends to apply a fairly uniform line weight throughout, which looks fine as a thumbnail and gets a bit flat once you're twenty minutes into colouring it in.

Real places are where it falls down hardest. I tried finding a colouring page of Tintagel Castle from one of the bigger AI-generated sellers and what came back was... castle-shaped. Turrets in roughly the right places. Nothing that actually matched the site itself. A decent illustrator working from reference photos gets the actual layout right - which window goes where, how the walls actually sit against the cliff.

Not every hand-drawn book is automatically good

Worth saying clearly - paying more doesn't guarantee quality, and plenty of AI-generated books are perfectly serviceable for an evening's colouring. I've also seen hand-drawn books let down by paper so thin the felt tip bleeds straight through to the next page, which has nothing to do with how good the illustration was.

What actually matters is the combination - real illustration work, paired with paper and binding that's been thought through properly.

Quick ways to check before buying

Look for whether the seller credits an actual illustrator by name. Most people who've genuinely commissioned an artist want you to know it.

Zoom into any sample pages. Repeated elements - windows, leaves, brick courses - are where AI tends to come unstuck under close inspection.

If the book claims to show somewhere real, search for a photo of the actual place and compare. Takes about ten seconds and tells you almost everything.

Check whether the listing mentions paper weight at all. Sellers who've thought about the whole experience, not just the pictures, tend to mention it.

Every illustration in our Britain In Lines books is drawn by a commissioned artist working from real reference photos of actual UK towns and landmarks - no AI tools anywhere in the process. You can see the full range in our colouring book collection.
