This one came to my mind, when i saw the symbol in the pizza box differentiating a Vegetarian Pizza and and a Non Vegetarian Pizza . The Vegetarian one had a Green colour and the other one had a Red Colour..
What does these colours signify..?
Green for vegetables and Red for the blood?
Is this a global representation used by the food outlets and manufacturers?
I remember seeing the similar green color symbol in a chocolate wrapper...
When i tried to Google for the global standard symbols, i was able to find a set of symbols for Vegetarian . But none for Non Vegetarians :(
