The blueberry cookies don't have any coloring added to them, that's how they look once you add the pureed blueberries to the mix.
I gave some cookies to some friends, and my family, they all liked the blueberry ones. They are more of a cakey cookie, rather than a crunchy one.
However, the lime cookies so far have been the overwhelming favorite.
I'm taking the rest to work tomorrow, we'll see what people say.
