Golf ball having color-shift effect

Abstract

A golf ball has a core, a cover layer, and a color-shift material incorporated into at least one of the cover layer or a coating applied to the cover layer. The golf ball also has an alignment indicator that provides an intended target strike location on the golf ball. The color-shift material causes the golf ball to exhibit a localized color-shift effect upon application of pressure in the form of a strike by a golf club. The color-shift effect comprises a shift between a first color and a second color and measured as a deltaE of greater than 2 when the change of pressure is within a target range. The color-shift material and the alignment indicator provide feedback regarding an actual strike location relative to the intended target strike location.
