Abstract
Sporting items such as soccer balls include a casing region and a graphic region that are defined by enhanced-visibility colors (EVCs) that are substantially complementary. Such EVCs can be selected to avoid colors associated with color confusion in color deficient individuals. In addition, such colors can be selected based on total reflectances to obtain a predetermined luminance contrast. EVCs can be selected based on separations of color coordinate locations using CIE chromaticity coordinates or CIE L-a-b coordinates or otherwise selected. Color selection can include consideration of anticipated viewing backgrounds in a general setting, or colors can be customized for a particular location and particular illumination conditions.
