Abstract: An improved fishing lure capable of presenting a unique visual impression by incorporation of a dichroic coating is disclosed. The dichroic coating provides a lure with unique visual properties including the appearance of having more than one color, especially when viewed from different angles or from transmitted to reflected light. The present invention thus provides a fishing lure incorporating dicrhoic coatings that transmit certain wavelengths of light, while reflecting others, thus creating an interference-effect similar to the iridescence observed in nature's fire opal, dragonfly wings and hummingbird feathers. The transmitted color is different than the reflected color, and when the light rays transmit straight through the glass they are less effected by refraction than when passing at an off axis angle, which make the light travel a greater distance through the glass. It is this distance that causes a color shift.
