Patent ID: 8360905

Claim:
A sporting object for use while in motion with an exterior surface, the exterior surface comprising: a casing region having a luminance L 1 ; and a graphic region having a luminance L 2 , wherein the graphic region includes a pattern graphic, the pattern graphic being provided in association with one or more axes for perception of ball rotation with respect to the one or more axes; wherein the casing region has a spectral reflectance associated with a first color of a pair of enhanced visibility colors (EVCs) and the graphic region has a spectral reflectance associated with a second color of the pair, the first color of the pair and the second color of the pair having representations on a CIE (1931) Standard Chromaticity Diagram that are offset in opposing directions from a representation of white with an expected illumination source used during competition, wherein the luminance contrast between L 1 and L 2 is greater than about 50%, and wherein the casing region and the graphic region are substantially non-reflective in a spectral window associated with a background for viewing the ball during competition.
