Coloring these mandalas can be an incredibly rewarding experience - both calming and satisfying. Each mandala contains intricate patterns and shapes that need to be carefully filled in with color to create a harmonious image. To achieve balance and symmetry, I would suggest mixing and matching complementary colors and tones for each shape. Start by choosing a light color for the entire design, then gradually fill in the darker tones to give depth and interest. Patterns can also be created by using fine, keenly placed strokes of one color. Once the mandala is complete, step back and appreciate the intricate beauty it has created.
