Swallowtail Specimen Iridescence vs Matte

Comparison of the front ♂ and back of the spring type of the Crow swallowtail butterfly specimen with spread wings. The amount of information in this illustration is that the structural color on the left and the butterfly on the right {argument name="color" default="matte brown"} are the same butterfly. If you write 'iridescent' on AI, everything will glow. The prompt's job is to distinguish between 'only here it shines, this part doesn't.'
