This mandala coloring page is quite intricate and beautiful. It is a circular design with a center, containing various geometric shapes as well as detailed designs. To bring out the colors of the mandala, I would recommend coloring it in layers, starting with the center then moving outward. I would begin by adding a neutral base color, like warm cream or grey, then layer colors with different hues to create a bright and vibrant appearance. The colors could range from subtle pastels to deep, dark shades, depending on the desired effect. With the intricate designs, using bright colors and calling colors that compliment each other will bring out the full beauty of the mandala.
