The photo above is of #4 Red green. Notice the different colors in the green. This is due to the ice and drainage patterns from the winter months. The darker areas are the wetter areas of the green. This same situation can hold true following heavy rainfalls throughout the year. This is why some locations on a green can be firmer than another.
