The blaze orange ones (e.g., Anderson River Park, CA) are very easy to see, but they look so unnatural. I voted for yellow (e.g., Horning's Hideout) because they're visible yet still seem to fit into the environment.
The blue powder coated mach 5's at four mounds come to mind. Those things are gorgeous. I think Gordy and Jayme each got one for each other if I remember right. Too bad the whole course isn't like that.

of the colors i have seen in person i would have to say the Powder coated Blue 1's that Pat Ferrell had.
Those powder blues are cooel!
Pat had nine of them he used to rent/loan to TD's back in the days when we had to set up baskets.
He is your friend, your partner, your defender, your dog. You are his life, his love, his leader. He will be yours, faithful and true, to the last beat of his heart. You owe it to him to be worthy of such devotion.
