Abstract
Golf club heads include white diffusing top surfaces to aid in club head alignment. Wood type club heads also include a dark diffusing club face so that a crown/face border is emphasized. Scorelines in wood type clubs can be provided with an intermediate contrast surface, and can be displaced from club face center to accommodate player perception when confronted with a white diffusing crown. Putter heads can include dark diffusing alignment lines, and iron-type club heads can include white diffusing surfaces at a sole portion of a club face, at a top line, or a top portion of a club face.
