A rendering method, based on high accuracy nano-optical simulations, is developed and applied to render the iridescent colors of the Morpho butterfly. The wings of the male display blue structural colors and backscatterings. In order to capture the Morpho butterfly features, subwavelength interactions on the scales must be rigorously taken into account. We calculate optical interference in the subwavelength scale structure using the high accuracy nonstandard finite-difference time-domain method, and validate the results by comparing with experimental measurements. Using our simulation results, realistic Morpho butterfly images are rendered.
