The Best Color by Number Apps in 2026 (Honest Roundup)

If you just want the short answer: Happy Color has the biggest library, Easybrain's Pixel Art is the classic pixel pick, and Pixfun is the one to watch if you want to generate your own puzzles with AI. This is an honest roundup, so full disclosure right away: Pixfun is our app, so weigh our bias accordingly. We will tell you where every app shines — including ours — and where each one falls short.

How did we pick and judge these apps?

We looked at the things that actually shape a calm coloring session: library size and freshness, whether the app is true pixel color-by-number or illustration paint-by-number, ad pressure, subscription pricing, and extras like photo import or AI generation. Where we mention user complaints, they reflect recurring themes in public reviews, not just our own testing. If you are brand new to the hobby, our pixel art coloring guide covers the basics first.

The best color by number apps in 2026

Eight apps made the cut. Each gets a fair verdict and a note on who it suits — no scores, no fake rankings.

Happy Color (X-Flow)

Happy Color is the giant of the category: a library of more than 40,000 pages, including officially licensed Disney and Marvel art you will not find anywhere else. It is free to play, and that is the trade-off — users report an intense ad load, with ads landing between pages and sometimes mid-session. One thing to know before you download: Happy Color is illustration paint-by-number, not pixel art. There is no grid, no chunky squares, no pixel reveal. Verdict: the right pick if you want the largest possible library and licensed characters, and you can live with heavy ads. If you are torn between the two styles, our Pixfun vs Happy Color comparison goes deeper.

Pixel Art: Color by Number (Easybrain)

This is the biggest brand in pixel-specific coloring, with a catalog of 20,000+ images and a photo-to-pixel camera feature that turns your snapshots into colorable grids. It is polished and dependable, and it has defined the genre for years. The recurring gripes in reviews are frequent ads and content that can feel stale between updates if you color daily. Verdict: the safest mainstream choice for classic pixel coloring with a huge back catalog. It suits steady, everyday colorers who value quantity and do not need creation tools. See how it stacks up in Pixfun vs Pixel Art: Color by Number.

Sandbox Coloring

Sandbox blends pixel color-by-number with a free-draw mode and a community gallery where people share their own art — a genuinely different mix. The catch is that it leans hard on its subscription: roughly $2.99 a week, $7.99 a month, or $39.99 a year after the trial, and much of the catalog sits behind membership. Verdict: a good fit if you want to color and also sketch your own pixel pieces, and you are comfortable paying for a membership. Less good if you mainly want a big free library.

UNICORN Color by Number

UNICORN's signature move is the time-lapse replay: finish a piece and watch it paint itself back in, ready to share. It also supports photo import, so you can pixelate your own pictures. The most common complaint is its aggressive weekly subscription pricing, which draws regular frustration in reviews. Verdict: suits people who love watching their finished art come alive and sharing the clips. Just read the subscription screen slowly before you tap. We compare the two in Pixfun vs UNICORN Color by Number.

Colorscapes (Artlife)

Colorscapes is a well-liked, curated paint-by-number app — illustrations, not pixels — with a noticeably lighter ad load than the big free players. The trade is a smaller library, so heavy daily colorers may run through the pages they like faster. Verdict: a calm middle path. It suits people who found Happy Color's ads exhausting but still want free illustration coloring with a numbered guide.

Lake

Lake is a different animal: premium, artist-drawn freehand coloring on iOS with a clear wellness focus. There are no numbers at all — you choose brushes and colors yourself, like a digital coloring book made by working illustrators. It costs more than anything else here. Verdict: for people who want expressive, unguided coloring and are happy to pay for artist work. If you rely on numbers to switch your brain off, this is not that.

Color Pop AI (MWM)

Color Pop AI is the closest thing to an AI rival in this list: it generates line-art coloring pages from text prompts and photos. But it is not a pixel color-by-number game — the output is illustration-style coloring — and users report heavy ads. Verdict: worth a look if you specifically want AI-generated line art to color freely. If you want AI generation plus the numbered pixel-grid puzzle, that combination is exactly what we built Pixfun for. Full breakdown in Pixfun vs Color Pop AI.

Pixfun (ours — bias fully disclosed)

Pixfun is our app, so read this verdict with that in mind. It is the only app in this roundup that combines color-by-number pixel play with prompt-based AI generation and photo-to-pixel conversion. Type it. See it in pixels: the AI Studio turns any prompt — say, "A brown owl peeking out of a hollow" — into a colorable pixel puzzle in about a minute, in ten styles from Kawaii to Cyberpunk to Noir. Around that sits a library of 1,000+ curated artworks across 15 categories, three canvas sizes from Easy 32×32 to Hard 96×96, and gentle progression: daily streaks, coins, XP, and a pixel cat named Pixie cheering you on. No timers, no move limits. It is free to download, with what we think is fair monetization — a Pro subscription from $3.49 a week to $39.99 a year with free trials, and a one-time $9.99 purchase that removes interstitial and banner ads forever. Verdict: if you want to make your own puzzles instead of only coloring someone else's, nothing else here does that. Pixfun is free to download on the App Store and Google Play.

Which color by number app should you pick?

Match the app to the one thing you care about most:

• Biggest library, period — Happy Color. Forty thousand pages is hard to argue with.
• Licensed Disney and Marvel art — Happy Color again. Nobody else has it.
• Classic pixel coloring with a huge catalog — Pixel Art: Color by Number by Easybrain.
• Coloring plus drawing your own pixels — Sandbox Coloring, if the membership fits your budget.
• Shareable time-lapse replays — UNICORN Color by Number, with eyes open on pricing.
• Artist illustrations and a calmer feel — Lake for premium freehand, Colorscapes for free numbered illustration.
• Making your own art with AI — Pixfun. From your photo to a puzzle, or from a one-line prompt.

Still deciding between two? Our comparison hub puts each matchup side by side.

There is no wrong pick here. Every app on this list can give you a quiet half hour of tapping colors into place, and that is the whole point.
