Claim:
A golf ball comprising a core and a cover covering the core, wherein a surface of the cover has a large number of dimples and a land that is a portion other than the dimples, when there are assumed: (1) an xy plane in which an x axis and a y axis indicate indexes a* and b*, respectively, in a CIELAB color system; (2) a circle that is present on the xy plane, has a center at an origin of the xy plane, and has a radius of 15; (3) four straight lines that are present on the xy plane and pass through the origin and whose intersection angles with adjacent straight lines are 45′; and (4) eight zones that are present on the xy plane and are located outside the circle and each of which is sandwiched between two adjacent straight lines, an xy coordinate of a hue of an outermost layer in the core excluding a colorless and transparent layer is included in any one of the eight zones, an xy coordinate of a hue of the cover is included in a zone that is different from the zone in which the hue of the outermost layer is included and that is different from a zone adjacent to the zone in which the hue of the outermost layer is included, and a ratio (T 1 /T 2 ) of a thickness T 1 of the cover immediately below a deepest portion of each dimple and a thickness T 2 of the cover immediately below the land is equal to or greater than 0.50 but equal to or less than 0.80.
