Why are salt pans pink?

My wife was recently in New Zealand and was greatly impressed by some pink salt pans. (Google for images using 'salt pans Blenheim' and you immediately get a superb example.)
Why are they pink? The two obvious ideas are (a) mineral content (If so which mineral?), or (b) algae. But does anybody know for sure?
