I've received a few inquiries as to why the greens are so many different colors of grass, and below is a quick read from an article I found at www.paceturf.org/ which is a trusted authority on turfgrass management:
As temperatures cool, some bentgrass plants produce the red pigment anthocyanin, a stress-response chemical. This behavior is restricted to only small patches of bentgrass, which are most likely clones that have segregated into small clumps of progeny that are not exactly the same as the parent variety that was originally planted.

Even the latest and best bentgrass varieties will segregate over time to yield patches of turf of diffferent texture, color or growth habit. Since the appearance of these patches is driven by the genetics of the plant, there is unfortunately little that can be done to manage it, other than to wait until environmental conditions favor more acceptable appearance of these clones.
The good news is that while these segregating clones do create a cosmetic disturbance, they rarely have any impact on playability.
