Colour by number, online — geometric and mandala designs
This is the real thing, not a preview of it — tap a colour below, then tap any numbered region to fill it. No download, no account, nothing to load first.
That's the same engine behind all six puzzles on this page — same one-tap fill, same tap-again-to-clear. Open this puzzle full-size, or keep reading for the rest.
Playing colour by number free online
Every one of the six artworks on this page is free to start and free to finish — the demo above proves it needs nothing but a tap. There's no app to download and no account wall before you begin: open a puzzle and you're colouring inside a second. A subscription (from £4.99/month) adds the children's activity library, premium finishes, extra layers and downloads, but nothing here requires it to colour by number online, free, today.
For adults: geometric and mandala, not photos
Most colour by number games rebuild a photograph or a pixel-art picture region by tiny region. RainbowShapeArt is built differently: every puzzle is an abstract geometric or mandala composition, so there's no hidden picture to uncover — the reward is watching the pattern's own symmetry and structure appear as you fill it. Play guided, where each region carries a number matching a colour in the palette, or switch to freestyle and choose any colour for any region, any time. Browse every puzzle.
For kids: a calmer, separate space
The puzzles above are built for adults and older children. For ages 4–8 there's a dedicated Learning for Children space instead, with its own shape-and-colour activities, a colour-mixing bench and short visual lessons on symmetry and pattern. It's deliberately calm and screen-quiet: no ads, no points, no timers, and nothing that tries to hold a child's attention longer than they want to give it.
Want a printable colour by number page?
These six puzzles are made for colouring on screen, not for printing — being honest about that rather than sending you to a print dialog that won't work well. If you'd rather colour on paper, the advanced studio generates original geometric patterns you can print instantly as an A4 or A5 outline. Get a printable geometric colouring page.
How colour by number works here
Each artwork is built from closed vector regions — anywhere from 128 in the smallest puzzle up to 486 in the largest — and a matching six-colour palette. In guided mode, every region shows the number of the colour it's meant to be; tap that colour, then tap every region carrying its number, and the shape fills instantly. Tap a filled region again to clear it. Complete a layer and you can add another one of fresh geometry on top, up to four layers deep, and you can pinch or scroll to zoom right into the smallest slivers at any point. Everything is saved to your device automatically, so a puzzle you leave half-coloured is exactly as you left it next time.

Questions people ask
Is colour by number free to play online?
Yes. Every one of the six artworks on this page is free to start and finish, right in your browser — tap the puzzle above to try it before you go anywhere else. A subscription adds the children's activity library, premium finishes, extra layers and downloads, but nothing here requires it to colour.
Do I need to download an app or create an account?
No. RainbowShapeArt runs in your browser on a phone, tablet or computer — there's nothing to install and no account to make before you start. Your progress saves itself on your device as you go.
Is there a color by number game for adults, not just kids' pictures?
Yes — that's what this whole site is. Instead of a hidden photo made of coloured pixels, every puzzle is an abstract geometric or mandala pattern from 128 to 486 regions. Play guided, where each region carries a number, or switch to freestyle and choose your own colours entirely.
Is this safe for children to use too?
There's a separate, calmer space for ages 4–8 at rainbowshapeart.com/children, built with its own shape-and-colour activities and no ads, no scores and no timers. It's a different product from the adult puzzles on this page, not the same one with a filter switched on.
Can I print a colour by number page instead of playing on screen?
The six puzzles on this page are built for on-screen colouring, not printing. If you'd rather colour on paper, the advanced studio generates original geometric patterns you can send straight to your printer as an A4 or A5 outline — see printable geometric colouring pages.
How is this different from typical colour-by-number apps?
Most colour-by-number apps rebuild a photo out of small numbered pixels, so the goal is uncovering a picture. RainbowShapeArt's regions are large, deliberate pieces of an abstract geometric or mandala design — there's no photo underneath, just the pattern's structure emerging as you fill it in.
