We stopped overseeding a few years ago and now use the pigments along with some liquid nutritionals to spray our tees, collars, approaches and fairways instead from about October to March. Total, we've sprayed probably close to 2,000 acres worth of product in the past 24 months. Because of this, we want to make sure we are getting the best bang for our buck, so for two years now I have tested just about every pigment product on the market on a test area on our driving range. The rates applied are label rates and mixed with the same nutritionals we apply to the fairways. We have found that almost every pigment provides for better turf health during the cooler months, regardless of manufacturer. Yes, some are better looking than others and some last longer than others, but when you break the price down to a per day basis, some are more economical than others as well. Green Pig ranked in the top 3 of all the ones we worked with.
I am not sure the pigments provide a cooler canopy to a measurable degree. I have only heard of one that touts this in their marketing (Turfscreen Original). However, I can not speak on this because we were applying to help warm the soil, not cool it.
Below is a photo of our trial area. This was early on in our trial and showed 8 products in 9 plots after the second application, two weeks apart. We ended up with 12 products in 13 plots by the end of the trial. You can see distinct differences between them. Some are more blue than others and one was virtually black. Most of these washed off the application equipment fairly easy while a couple stained bad. I still have green in the back of my cart from December from a product touted as a pigment.

This is a photo of our fairways in march after receiving 13 sprays starting in late October. We had already received about 23 frosts at this point, with a few of them in the lower 20's for an extended period. In this photo the rough is just waking up from dormancy.
