Adult colouring books have been one of the most sustained creative trends of the last decade — and the marker question they generate is slightly different to the question an illustrator or fine artist asks. When you’re colouring in a pre-printed design, the priorities shift: blendability matters enormously because smooth colour transitions are the whole point of the exercise, bleeding through thin colouring book paper is a genuine practical problem rather than an abstract concern, and ergonomics matter more than many people expect because colouring sessions run long and uncomfortable markers cause hand fatigue. The best marker for an illustrator and the best marker for an adult colouring book enthusiast can be completely different tools.
I run Discount Art Supplies — a price comparison and deals platform with 41,000 UK artists across our community. Before that I spent nearly a decade as Digital Marketing Manager at ARTdiscount, one of the UK’s largest online art retailers, watching what people actually bought and what they came back for. Markers for colouring books came up constantly — and the questions were always the same. Do they bleed? Will they blend? Are they worth it? This guide answers all three honestly.

⭐ Best Markers for Colouring — Quick Picks
Best overall for colouring books: Ohuhu 168-Colour Alcohol Markers — the most recommended set for adult colouring books in 2026. Dual tip, excellent blending, enormous colour range, genuinly good value.
Best professional colouring markers: Copic Ciao Markers — the affordable entry into the Copic system, refillable, 180 colours, the professional colouring standard.

Best mid-range alcohol markers: Prismacolour Premier Dual-Ended Markers — rich, vibrant alcohol ink, excellent blendability, a significant step up from budget markers without Copic prices.
Best UK brand for colouring: Winsor & Newton Promarker — widely available in UK art shops, 189 colours, dual tip, the familiar UK professional option.

The Bleed-Through Problem — What You Need to Know First
The single most common frustration with colouring book markers is bleed-through — ink soaking through the page and ruining the design on the other side. It’s a genuine practical problem that affects which markers are worth buying for colouring books specifically, and it’s determined by two factors: the type of ink and the weight of the paper in your colouring book.
Alcohol-based markers bleed through thin paper. This is not a defect — it’s a characteristic of the ink type. Alcohol ink is designed to flow smoothly and blend, and that same fluidity means it penetrates thin paper. Most colouring books are printed on 70-90gsm paper, which is too light for alcohol markers without bleed-through. The solutions are either to use heavier paper colouring books (ideally 160gsm+), to place a blank sheet behind the page you’re colouring, or to use water-based markers instead of alcohol-based ones.
Water-based markers — Tombow Dual Brush Pens, Staedtler Triplus Fineliners, Faber-Castell brush pens — don’t bleed through standard colouring book paper and are genuinly the right choice if bleed-through is a concern. The trade-off is that water-based markers don’t blend as smoothly as alcohol markers and the colours aren’t as vibrant. For anyone who primarily colours for relaxation and doesn’t want to think about paper weight, water-based markers are the more practical starting point.
Ohuhu — The Best Value Colouring Markers in 2026
UK Price Comparison
🔍 Compare Ohuhu Prices →The Ohuhu 168-colour set is the most consistently recommended marker set for adult colouring books across independent reviews in 2026 — and the reasons are specific to the colouring use case. The colour range at 168 colours covers virtually any palette a colouring design requires. The dual brush and chisel tips suit both broad filling and fine detail work within the same marker. The blending is genuinly good — smooth colour transitions that the colouring community specifically prizes — without Copic prices. My son Zach has been using a smaller Ohuhu set since Christmas and the blendability surprised me given the price point.
The honest caveats are consistent with all alcohol markers: bleed-through on thin paper requires a backing sheet or a heavier paper colouring book, and there’s a mild odour when wet. For colouring specifically, the 168-colour range means you’re unlikely to need a second set for colour variety, which makes the economics particularly attractive compared to building up a Copic collection gradually.
Copic Ciao — The Professional Colouring Standard
UK Price Comparison
🔍 Compare Copic Prices →Copic Ciao is the entry point into the Copic system — the same ink and refillable design as the professional Copic Sketch at a slightly lower price point per marker, with 180 colours available. For serious colouring book enthusiasts who want the best possible blending performance and are prepared to invest in a system that lasts indefinitely through refilling, Copic Ciao is the honest recommendation. The blending between Copic colours is genuinly superior to any other alcohol marker at any price — building a Ciao collection gradually, colour by colour, is how most dedicated colouring book artists approach the investment.
The honest caveat is cost — Copic Ciao markers are considerably more expensive per marker than Ohuhu. For someone new to colouring book markers, Ohuhu is the more sensible starting point. For someone who’s been colouring seriously for a year and knows exactly what they want, Copic Ciao repays the investment.
Tombow Dual Brush Pens — Best for No Bleed-Through
UK Price Comparison
🔍 Compare Tombow Prices →Tombow Dual Brush Pens are water-based rather than alcohol-based — which means no bleed-through on standard colouring book paper and no odour, making them genuinly the right choice for anyone who wants to colour without worrying about managing paper weight or backing sheets. The dual tip (flexible brush tip and fine liner tip) suits detailed colouring work, and Tombows blend beautifully with a water brush pen which allows smooth colour transitions without alcohol ink. The 108-colour range covers most colouring palettes well.
The honest trade-off versus alcohol markers is that the colours are slightly less vivid and the blending — while good — doesn’t quite match the smoothness of Copic or Ohuhu. For relaxation colouring with no technical complications, Tombow is the most practical recommendation. For colouring enthusiasts who want maximum vibrancy and blending performance, alcohol markers on heavier paper are worth the extra consideration.
Prismacolour Premier — Best Mid-Range Alcohol Markers
UK Price Comparison
🔍 Compare Prismacolour Prices →Prismacolour Premier Dual-Ended Art Markers sit between Ohuhu and Copic in both price and performance — advanced dye-based alcohol ink with rich colour saturation, excellent blendability and smooth consistent flow, dual tip with fine and chisel ends. Not refillable unlike Copic but consistently praised for vibrancy and blending quality. For colouring book enthusiasts who’ve outgrown budget markers but aren’t ready to commit to Copic prices, Prismacolour Premier is the natural mid-range step up.
Winsor & Newton Promarker — The UK Favourite
UK Price Comparison
🔍 Compare Promarker Prices →Winsor & Newton Promarker is the most established professional alcohol marker from a UK art brand and the familiar option for UK colouring book enthusiasts who want to buy locally rather than ordering internationally. 189 colours, dual tip, alcohol-based ink that blends well and produces vibrant, consistent colour. Available individually which matters for replacing specific colours that run out during long colouring sessions. The blending is slightly less smooth than Copic but considerably better than budget alternatives, and being available in Hobbycraft and most major UK art retailers makes restocking straightforward.
