Hat Trick

You and your two friends, Juan and Juanita, open a box with five hats in it. Three of the hats are blue, and two of the hats are yellow. The three of you close your eyes and take one hat each out of the box. With your eyes still closed, you each place the hat you're holding on your head. When you open your eyes, you see that both Juan and Juanita are wearing blue hats.

Juanita asks Juan if he knows what color his hat is. Juan says, "I don't know." Juanita replies, "Oh, then I must be wearing a blue hat."

What color is your hat?
