Dan,
After holding out for almost 7 years, I gave in and now use the green dyed sand. No benefit agronomically, and actually less beneficial over the 80/20 sand/compost mix I used to use. But, it does hide better when used.
Personally, I'd prefer to use the 80/20 mix above, and possibly add a bit of colorant in with it. But, the cost is astronomical.
