Number 6.  Instantly recognisable if you drove past a billboard with it on and it caught your eye only for a split second.  When it comes to logo design; think Nike and Apple. Clear, uncluttered, instantly recognisable from a distance.  In addition this logo also contains Gestalt principles within it's design which is used a great deal in modern marketing.   In short Gestalt psychology states that we see things as a whole rather than a sum of its parts.  The lines and curves in the central design clearly create an image that can be perceived as a tree or a leaf.  The Gestalt principle of closure often leads consumers to pursue a further search for information on what they are seeing i.e seek confirmation if what the design represents / actually shows and it is a very powerful way of capturing consumers attention and then creating the opportunity for exposure to the product / service.   Exposure leads to learning, leads to evaluation, leads to use / consumption.  Without the initial exposure the next steps cannot take place.  A person who is ecologically conscious is more likely to be attracted to this design because the tree/leaf has a conscious or subconscious importance in regards their beliefs / attitudes towards environmental issues. I would imagine this is the type of person Carboncoin wishes to attract and this type of person is highly likely to use / invest in the coin as it has a strong affinity with their values / ethical stance. 

That is why I am particularly impressed with this logo. A great deal of thought has gone into the design by the creator.  

I make this statement with confidence as I am reading for my masters degree in marketing
