Halo eye makeup places deep matte shades on the inner and outer corners while spotlighting the center with bright metallic copper, making brown eyes sparkle. Map out the eye shape by applying a matte dark chocolate brown shadow to the inner third and outer third of the eyelid, leaving the exact center of the lid blank. Connect the inner and outer dark zones lightly through the crease with a warm terracotta transition shade. Pat a dense, metallic copper or warm bronze shimmer shadow directly onto the center blank space using a flat packing brush or fingertip. Blend the edges where the metallic center meets the dark corners to ensure a smooth gradient. Highlight the inner tear duct with a bright gold shimmer to complete the multidimensional dimensional effect.
