An exemplary fishing lure evaluation system includes a light transmission element, such a red-free green filter of 50% transmissivity, arranged relative to a light source for illuminating the lure under evaluation primarily with light transmitted through the element so as to reproduce the natural underwater illumination for the lure including the effects of the water coloration and the light level preference of the type of fish targeted. Preferably, a viewing element is included through which the lure is observed, such as a clear lens or red-free green filter of 50% transmissivity, to duplicate the effects of the water between the fishing lure and the fish for a nominal presentation distance. Specific forms of the invention include an assortment of filters for use with a conventional flashlight or, alternatively, a lightweight plastic tube having, for example, red-free green sides, an open end and a clear condensing lens at the opposite end to reproduce the primary winter feeding conditions for steelhead or salmon for short or long presentation distances depending on whether the user views the lure through the lens or the sides, respectively. The system permits evaluation of all types of lures including homemade lures, fluorescent lures and multicolored lures. A standard proven effective for the local fish population, such a natural food specimen, can be used to select a color attractive to this population, or the system can be used to grade the lures according to how well they hold their apparent color when observed with the system.
