I didn't think it made much sense when I posted the question, but I know how some of the more experienced people on the board are always experimenting. Plus rack-attack was right, it is a way to save money since these things are $20 for 36 of them. I like to use 2 different color vanes on my arrows, so I would need to order 2 packs. That is $40 plus shipping so you are looking at almost $50 in just vanes. Pretty pricey in my book.
After saying all that I did order one package of orange, and if I see results I will order another pack of a different color.
