Peacock blue is a vibrant and iridescent color often associated with the feathers of the孔雀 (peacock). When used in a metallic pairing, it typically refers to a sleek and glossy finish that reflects the blue and green hues of the peacock's tail. Pairing such a color with other elements would require careful consideration of complementary or contrasting colors to enhance the visual appeal. This could involve neutral tones, other shades of blue, or even bold colors like red or gold. An image pairing would illustrate how these colors are combined in a design context.
