Often associated with mold and decay, the color blue is typically not a popular one when it comes to all things food related. That's why you won't see too many blue plates in restaurants -- just not too appetizing, say food experts. Interestingly, you don't typically see too many blue foods either. Well, in Ireland you might. And other places too if you really look around. But let's stick with the Irish story.

The blue potato, once introduced by a family producing vegetables for 200 years, became all the rage in Dublin not long ago, where parents began urging kids to eat their blues.

Who knew the blue potato -- the color comes from the antioxidant anthocyanin -- would be such a hit when marketed to the masses. The idea was to appeal to children by selling them something with a little novelty. It worked -- initially. But interest may be waning. Why? The color.

How do you feel about blue? I'm OK with it. I like blueberries and blue chips, and well, I can't really think of anything else. Blue potatoes? I'd try them. How about you?
