Color is not claimed as a feature of the mark.
The mark consists of a stylized number "9" with a silhouette of a golf ball inside of the loop. The lower section of the number has a line added on to it to make it look like the ball is sitting on top of a golf pick. Below the image is the phrase "BACK9" in upper case letters followed by the phrase "TURF & PUTTING GREENS" below, also in upper case letters.
