Are blueberries blue or are they purple?
Blueberries are considered to be indigo-colored so they are more purple than blue. They are perennial flowering plants of the genus Vaccinium. For more information, visit http://en.wikipedia.org/wiki/Blueberry.
They look purple to me.
Blue but some have purple blotches.
According to blueberries.com (not a wiki source) they can range in shades from deep BLUE to deep red. http://www.blueberry.org/faq.htm
