This Peacock Butterfly is so beautiful! The wings have a unique blue sheen on a dark brown background and there are two eyespots on each wing, with black centers and either white or pale blue rings around them. The undersides of the wings are a pale brown. The body is dark brown, too. To bring out the beauty of this butterfly, I would start by coloring the eyespots in black and then move outwards to the white or pale blue rings. For the wings, I would use a combination of blue and brown, starting with light shades and gradually build up to darker shades. To give it dimension, I could even try out some shading and highlighting techniques. Finally, I would use a dark brown to color the body.
