holiday help, please . . .

Okay, I am looking for a little help! I was going to knit the twisted rib hat for all my employees this year, in addition to their bonus. It is the pink/orange and blue hats in the photo. Now I am starting to second guess myself. I have enough Blue Sky Alpaca to knit each one a hat - twisted rib or otherwise. So here are the two options
1. each one gets a twisted rib hat in a different color
2. there are two or three hat pattern all hats knit in different colors

Thanks for your opinions!
