of the ones you posted i like citron and tangerine...on a side note, I have one (black) and I loooooooooooooove it..I have so much fun cooking with it.
Not to totally hijack the post, but MissMee--they have a pasta attachment for the KitchenAid mixer and it's great!!! I just got my husband one for his birthday and it makes great pasta. You have to break yours out of the box--it's the best mixer ever.
Cortney--I like the ice one as well. We have the red one and I love having a burst of color in what is otherwise a pretty boring kitchen.
