Pick a color and tap a shape. With symmetry fill on, every matching shape around the circle fills at once — or print a blank mandala and color it by hand.
How it works
Choose a detail level and, if you like, a fixed symmetry (6 to 24 repeats); "New mandala" draws a fresh design every time. Tap a shape to fill it with the selected color. Symmetry fill colors all copies of that shape around the circle in one tap — switch it off to color shapes one by one. Undo reverses the last tap, even when it filled a whole ring. "Print blank" prints only the lines on one A4 page, "Print colored" prints your artwork, and "Save PNG" downloads a 1200 × 1200 image.
Mandala is a Sanskrit word usually translated as "circle". In Hindu and Buddhist traditions it names a sacred diagram built outward from a centre, and Tibetan monks still make elaborate sand mandalas that are swept away once finished. Today the word is also used far more loosely for any design of shapes repeated in rings around a middle point, and that looser, decorative sense is what this page offers: geometric patterns to color, not religious images.
How the designs are built: rings and symmetry
Every mandala here is made of a few concentric bands. Each band holds one motif — a petal, leaf, drop, star, diamond, crescent or circle — repeated the same number of times all the way round. That number is the symmetry: with 8, the whole design looks the same after an eighth of a turn. Low symmetry (6 or 8) gives big, easy shapes; 16, 20 or 24 gives a fine, lace-like ring. Alternate bands are rotated by half a step so their motifs sit between those of the band next to them, which is what makes the rings interlock instead of lining up in spokes.
The three detail levels change how many bands there are and how fine they get. Easy uses two or three wide bands and low symmetry, good for a phone screen or a first try. Medium is the everyday choice. Detailed adds five to seven narrow bands, higher symmetry and small beads along the ring lines; its shapes are small, so it is best printed or colored on a tablet or computer.
Choosing colors for a mandala
Because the same shape repeats around the circle, color choices show up as rings rather than as single spots, so a small palette usually looks better than a large one. A few approaches that work well:
Light to dark: start pale in the centre and darken band by band toward the edge, or the reverse, for a glowing or a framed look.
Two families: pick a warm group and a cool group and alternate them between neighbouring bands so each ring stands out.
Shape and gap: color a motif and the band behind it in contrasting shades — dark petals on a light band, or the other way round.
Use the presets as a starting set: Pastel and Ocean give calm results, Sunset and Rainbow lively ones, Forest and Earth natural tones.
Coloring as a quiet break
Many people color mandalas simply because the repetition is absorbing: there is always an obvious next shape, no drawing skill is needed and a design can be finished in ten or fifteen minutes. Some small studies have reported that coloring structured patterns can feel more relaxing than free drawing, but the evidence is limited and coloring is not a treatment for anything. Think of it as a calm, screen-light activity — especially on paper — rather than as therapy.
Printing tips
"Print blank" sends only the line drawing to the printer, sized to fit one A4 page with the mandala number underneath, so the colors you have already added on screen are left out. In the print dialog choose 100% or "fit to page" and switch off headers and footers for a clean sheet. Colored pencils and fine felt-tip pens suit Medium and Detailed designs; for Easy designs, crayons work too. Thicker paper (around 120 g/m²) stops markers from bleeding through. If you want a set, generate and print several mandalas in a row — each "New mandala" is a different design.
Yes. Coloring on screen, saving PNG images and printing blank or colored mandalas are all free, with no sign-up and nothing to install. It works in any modern browser on phones, tablets and computers.
What does symmetry fill do?
With symmetry fill on, tapping a shape colors every copy of that shape in the same ring, so a whole circle of petals changes in one tap and the design stays perfectly balanced. Switch it off when you want to color shapes individually, for example to make alternating colors. One Undo reverses the whole ring.
Can I print a mandala to color by hand?
Yes. "Print blank (A4)" prints just the outlines on a single A4 page, even if you have already colored some shapes on screen. "Print colored" prints your artwork as it looks now. Both leave out the buttons and the rest of the page.
Which detail level should I choose?
Easy has two or three wide rings and big shapes, which suits small phone screens, younger colorists and crayons. Medium is a balanced default. Detailed has up to seven narrow rings and up to 24-fold symmetry; the shapes are small, so it is most comfortable printed or on a larger screen.
Will I ever see the same mandala twice?
Practically never. Each design is generated from a random seed that picks the symmetry, number of rings, the motif in every ring, its size, the border and the centre. You can fix the symmetry from the menu and still get a different arrangement every time.
How do I save my colored mandala?
Tap "Save PNG" to download a 1200 × 1200 image with a white background. On phones the share sheet opens so you can save it to your photos or send it. The page does not keep your work after you leave, so save before starting a new mandala.
