Colour is used expensively by retail, marketing and packaging industries in order to convey messages and sensations or trigger associations which encourage the consumer to buy their products. Packaging has to provide all the attraction and all the information necessary for the customer.

Blue - is not found in food packaging because people want to associate the color of the package with the color of product. But, some companies use blue to stand out against the other brands.

Yellow - most popular brands use this color. Yellow is the fastest color the brain processes, and therefore is usually a good attention getter. It is also an appetite stimulant and tends to make people feel cheerful and optimistic.

Red - tends to make people feel excited, full of energy, and can actually increase the heart rate. Like yellow, red is also an appetite stimulant, and warm and inviting color.

Green - the color of nature, a feeling of healthiness, fewer calories, more protein, and less fat

Black - a sense of elegance, wealth, and sophistication, not popular in food packaging, use to make other colors stand out
