Even with paint, I wouldn't expect more than about 90-100 days at the most. With the new pigments (i.e. Foursome, Par, Envy, Green Pig, etc...), our on-site data shows color lasting about 2-3 weeks on average. This is all related to irrigation, rainfall, growth and mowing. If you used a dye, I'm surprised you got more than a few days.
