Geometric Mandala Triangles Coloring Page for Adults

Adults 18+Mandala

This adult mandala coloring page features a bold geometric design built from concentric rings of triangles, diamonds, and hexagons. The center starts with a small hexagon, then expands outward through alternating facets and leaf-like motifs. You’ll love the perfectly continuous, gap-free outlines that keep every ring crisp and symmetric. A fun detail: the outermost band blends star shapes with tessellated diamond segments for extra sparkle

Coloring Tips

Color the center hexagon first—try a dark teal or deep violet—then build outward with alternating warm (coral, amber) and cool (aqua, sapphire) ring colors to make the radial symmetry pop.

Use a light-to-dark gradient on each ring: shade one side of triangles and diamonds slightly darker to create a faceted 3D look.

For the leaf-like and curved petal shapes, blend two close tones (e.g., mint + lime) using colored pencils with gentle overlap along the motif edges.

Try gel pens or metallics on the outermost stars and tessellated diamonds—gold or silver looks great against the consistent black linework.

Keep line weight consistent by coloring small adjacent sections at a time, using a fine-tipped pencil for intricate interlocking polygon facets so gaps don’t appear between patterns.
