The white colour in the butterfly family Pieridae is a derivative of uric acid, an excretory product. [13] [40]: 84 Bright blues, greens, reds, and iridescence are usually created not by pigments but through the microstructure of the scales.
The butterfly eye is similar to the average insect eye in that it is composed of numerous ommatidia. Each butterfly ommatidium contains nine photoreceptor cells with generally each cell using a single opsin. [6] With a UV sensitive opsin the butterfly can see UV light and respond maximally to ultraviolet light at approximately 350 nm. [6]
The brilliant iridescent colors of the peacock's tail feathers are created by structural coloration, as first noted by Isaac Newton and Robert Hooke.. Structural coloration in animals, and a few plants, is the production of colour by microscopically structured surfaces fine enough to interfere with visible light instead of pigments, although some structural coloration occurs in combination ...
A transparent flag (scrim) with light shining through it Flags come in a wide variety of shapes and sizes, from mere square inches ("dots and fingers") to many square feet ("meat axes").
