HIGH VISIBILITY SAFETY ORANGE WITH REDUCED VISIBILITY TO DEER AND OTHER DICHROMATIC ANIMALS

摘要

The present invention relates to a material with high visibility to humans and low visibility to deer and other dichromatic animals, and a method for making the same. The color “Safety Orange” emits and reflects light at the long visible wavelengths of 595-605 nm, which are conspicuous to humans and largely unseen by dichromates. Common manufacturing and laundering practices cause existing Safety Orange products to also emit strongly at 455 nm and 496 nm, the peak sensitivity of deer blue cones and deer rods respectively. The present invention differentially reduces light emission and reflection at wavelengths below 500 nm for decreased visibility to dichromatic animals. This differential reduction preferably incorporates a pattern, such as a camouflage pattern, to further reduce visibility to deer. This pattern is preferably visible to dichromates while remaining largely invisible to humans.
