Colour plays a significant role in our perception of food, influencing our appetite, taste expectations, and overall eating experience. The psychological and physiological effects of food colours are essential considerations in food science and marketing.
How Colours Affect Appetite

Stimulating Appetite: Certain colours can stimulate appetite and make food appear more appealing. | Suppressing Appetite: Some colours can have a calming effect or be perceived as unappetizing, leading to reduced appetite. | Enhancing Flavour Perception: Colours can affect how we perceive the flavour of food. For example: |
Red: Often associated with excitement and energy, red can increase heart rate and stimulate hunger. It's commonly used in fast food branding and packaging. Yellow: A bright, cheerful colour that can evoke feelings of happiness and encourage eating. It's also used in many food brands to attract attention. Orange: Combines the stimulating effects of red and yellow, creating a warm and inviting feel that can enhance appetite. | Blue: Rare in natural foods, blue is often associated with spoilage or artificiality. It's considered an appetite suppressant and is rarely used in food marketing. Purple: While it can denote luxury and creativity, purple is also uncommon in natural foods and might suppress appetite when overused. Black: Can convey sophistication and elegance but is generally not appetizing for most foods. | Green: Associated with freshness and health, green can make food appear more nutritious and flavourful, especially in salads and vegetables. Brown: Often linked to rich, savoury, or roasted flavours, brown can enhance the perception of taste in foods like chocolate, coffee, and grilled meats. |
Psychological Mechanisms
Learned Associations: Our brains develop associations between certain colours and specific tastes or food experiences over time. For instance, we might associate yellow with lemons or bananas, leading us to expect a sour or sweet flavour.
Cultural Influences: Cultural background can influence how we perceive food colours. In some cultures, white may be associated with purity and celebration, while in others, it might be linked to mourning.
Visual Expectations: The colour of food sets up expectations about its flavour and quality. If the colour doesn't match our expectations (e.g., a green strawberry), it can create cognitive dissonance and affect our perception of taste.
Practical Applications
Food Presentation: Chefs and food designers use colour to make dishes more visually appealing and to enhance the dining experience. A colourful plate with a variety of hues can make a meal more appetizing.
Product Development: Food manufacturers carefully choose colours for their products and packaging to attract consumers and influence their buying decisions. Natural and artificial colourings are used to achieve the desired appearance.
Marketing and Branding: Companies use colour psychology in their branding and advertising to evoke specific emotions and encourage consumption. For example, many fast food chains use red and yellow in their logos to stimulate appetite and attract customers.
Interesting Facts
Colour Blindness: People with colour blindness may perceive food differently, which can affect their appetite and food choices.
Lighting Conditions: The colour of lighting in a dining environment can alter the perception of food colours. Warm lighting can make food appear more appealing, while cool lighting might suppress appetite.
