Our concerns about leaves have us divided because of a company in the allergy-foods field also called Pure (
http://www.puredairyfree.co.uk/). We haven't said no leaves, we're just wary of the fact that we might end up causing consumers to think we're linked somehow. As the colours of the logo will change, we are thinking that perhaps the best way to avoid confusion is to not ever have green leaves, just other colours. So whilst we have green leaves in the top ranked designs, we will change the colours if a leaf-based-design wins the contest... rather like leaves change in the autumn! I hope that clears things up!
