Crystal Pyramid Coloring Page

Enjoy a free printable coloring page full of triangles – from a crystal pyramid and winding river to a triangular sun and staircase. Kids love the bold line art, and it’s a great way to explore geometry while having fun.

What's Happening

Look at the towering crystal pyramid sitting in a field of interlocking triangles. Its glass‑like facets catch the light, and around the base a river of hollow arches winds like a ripple, each opening to a glowing triangular moon. Above, the sky is dotted with angular clouds shaped like perfect isosceles triangles, all drifting toward a huge triangular sun that sprays concentric rays.

How to Have Fun

Grab your favorite crayons or markers and start with the pyramid – try a mix of cool blues and purples to make those facets sparkle. The river arches give a chance to blend some soft glows for the moons, while the clouds are perfect for experimenting with pastel shades. Don't forget the spiral staircase made of stacked equilateral triangles; each step can be a different color for a rainbow effect as it climbs toward the sun.
