Manufactures of crisp products need a way to ensure that the overall colour of their products are the same from bag to bag.
Seasonal changes can alter the base colour and the consumer predominately perceives:
· Green Crisps as early harvested or Mouldy
· Light Crisps as not cooked
· Dark Crisps as over cooked
The company needs to produce the product to a certain target as colour & appearance perception influences the customers buying decision.
