Color and Taste

Color and Taste | Science Fair Projects | STEM Projects
Ever wonder why food and beverage manufacturers put so much effort into finding the perfect color and texture for their products? Let's find out by conducting an experiment to see if the color of a beverage affects how it tastes!


The hypothesis is that most people’s perception of taste will be based on the color of the beverage.

Method & Materials

You will need to gather all the materials, then mix equal amounts of soda water and lime juice and the same servings of sugar into all 4 jugs. A few drops of red food coloring is added to the first jug until a tempting red color is obtained. Orange food coloring is added to the second jug and purple food coloring is added to the third jug. The fourth jug will remain clear without any coloring. The jugs are kept in a refrigerator overnight. On the second day of the experiment, the 4 jugs of beverage are brought out of the refrigerator for testing. Each type of drink is poured into 20 paper cups. The 20 participants are each given 4 cups containing the different colored drinks and a form to fill in their choice.
You will need 20 participants, 80 plastic cups, 3 types of food coloring, 4 jugs, 1 kg sugar, 4 bottles of lime juice, 4 bottles of soda water, 1 refrigerator, 20 forms to fill, and 1 black marker pen.


The results show that most of the participants had selected the flavors of the drinks based on the color. This proves that the hypothesis is true - most people’s perception of taste will be based on the color of the beverage.

Why do this project?

This science project is interesting because it shows how our past experiences and what we have seen in advertisements can influence our perception of taste.

Also Consider

Possible variations for this project include testing various juices (apple, grape, pear) versus adding the same food coloring dye in them, or using a clear flavored jello with red and yellow food coloring (see video below)
