Every spring Meyer zoysiagrass goes through a seeding stage. During this stage, the seedheads are visible and the fairways are not very attractive to the eye. The seedheads give the fairways a purplish appearance, especially when they go unmowed for several days. I have added some pictures below to help illustrate. The seedheads should subside in a couple of weeks when we get more consistent warm temperatures.
the reddish-black tinge is very noticeable in this view of #6 fairway
the seedheads can easily be distinguished in this up close view
