Abstract
The present invention relates to a golf ball having a core, a cover of at least one layer encasing the core, and a surface on which a plurality of dimples are formed. The cover has an outermost layer with a thickness of at least 1.2 mm and a Shore D hardness of at least 50 but not more than 65. The ball surface has a lightness L value, expressed in the Lab color system as defined by JIS Z8730, of at least 89, an a value of at least 2 but not more than 10, and a b value of −20 or above. Increasing the reddish coloring of a white golf ball enhances the fashionability of the ball and improves the way the ball looks and feels to the golfer when it is played.
