This Mandala Coloring Page is stunningly beautiful! I would start by coloring the Muladhara symbol in the center a vibrant red, yellow, blue and white to create a powerful contrast with the surrounding circles. The eight circles representing the chakras can be filled in with the varying colors of orange, green, pink, purple, blue, and brown. This combination of vibrant colors creates a wonderfully aesthetically pleasing look while also adding an extra layer of spirituality to the design. For the outermost circle of the mandala, I would choose a bold black and gray pattern to draw attention to the entire composition.
