Here's my latest hat pattern - it features a braided edge and uses three colors. (It is HERE on Ravelry and HERE at the Lulu store.) Below is the women's size in Brown Sheep Nature Spun sport weight - Snow, Evergreen, and Butterfly Blue which is my favorite yarn color of all time.
This is the men's extra-large version for DH knit in organic Vermont O-Wool Classic in Cornflower, Saffron, and Sky.
The hat has a very easy four point top.
