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. ## Claims ### Claim 1 A golf club head, comprising: a crown having at least an upward facing surface portion provided with a diffused surface treatment as viewed from an address orientation, wherein the diffused surface treatment defines a highest reflected intensity location on the crown in response to illumination from a light source situated within a cone of angular radius of about 30 degrees above the crown, further wherein a secondary location situated on the crown at a distance of at least 20% of a crown effective length from the highest reflected intensity location has a reflected intensity of at least 25% of the highest reflected intensity; and a striking surface situated so as to define an interface with the crown. ### Claim 2 (depends on 1) The golf club head of claim 1, the crown effective length is selected from a plurality of pixel radii having a 30 degree angular spacing and radiating from the highest reflected intensity location to an edge of the crown. ### Claim 3 (depends on 1) The golf club head of claim 1, wherein the crown effective length is associated with a toe-to-heel direction. ### Claim 4 (depends on 1) The golf club head of claim 1, wherein a zone of crown intensity is defined from the crown effective length in a direction of 30 degrees and negative 30 degrees from the crown effective length orientation, wherein the reflected intensity is at least 20% of the highest reflected intensity within a distance of at least 20% of the crown effective length from the highest reflected intensity location. ### Claim 5 (depends on 1) The golf club head of claim 1, wherein the secondary location is situated on the crown at a distance of at least 30% of the crown effective length from the highest reflected intensity location. ### Claim 6 (depends on 1) The golf club head of claim 1, wherein the secondary location is situated on the crown at a distance of at least 40% of the crown effective length from the highest reflected intensity location. ### Claim 7 (depends on 1) The golf club head of claim 1, wherein the secondary location is situated on the crown at a distance of at least 50% of the crown effective length from the highest reflected intensity location. ### Claim 8 (depends on 1) The golf club head of claim 1, wherein the secondary location is situated on the crown at a distance of at least 60% of the crown effective length from the highest reflected intensity location. ### Claim 9 (depends on 1) The golf club head of claim 1, wherein a plurality of secondary locations are situated on the crown at distances of at least 50% of the crown effective length along a respective plurality of pixel radii situated at angles of at least 30 degrees with respect to each other such that the secondary locations are situated on the crown a distance of at least 50% of a respective pixel radii and are associated with reflected intensities of at least 50% of the highest reflected intensity. ### Claim 10 (depends on 9) The golf club head of claim 9, wherein the secondary locations are situated on the crown a distance of at least 75% of the respective pixel radii and are associated with reflected intensities of at least 70% of the highest reflected intensity. ### Claim 11 (depends on 1) The golf club head of claim 1, wherein the diffused surface treatment is a white surface treatment associated with a gloss value of less than about 60. ### Claim 12 (depends on 1) The golf club head of claim 1, further comprising a transparent matte coating situated on at least the upward facing portion of the crown, wherein the transparent matte surface is a semigloss or low gloss surface. ### Claim 13 (depends on 12) The golf club head of claim 12, wherein the transparent matte coating has a gloss value of less than 60 gloss units. ### Claim 14 (depends on 1) The golf club head of claim 1, wherein at least the upward facing portion of the crown surface has a chroma value of less than 5. ### Claim 15 (depends on 14) The golf club head of claim 14, wherein at least a top portion of the face surface adjacent the crown has a black surface treatment. ### Claim 16 (depends on 15) The golf club head of claim 15, wherein at least the top portion of the face surface has a gloss value of less than 50 gloss units. ### Claim 17 (depends on 15) The golf club head of claim 15, wherein the black surface treatment has a chroma of less than one and a brightness of less than 50. ### Claim 18 (depends on 1) The golf club head of claim 1, wherein the face surface has a black surface treatment having a chroma of less than 1.0 and a brightness of less than 50, and at least the upward facing portion of the crown surface has a chroma value of less than 5 and a brightness greater than 85.
