The impact of color on the experience of food was highlighted during the seventh season of Julia Child's The French Chef, the first to be broadcast in color. Dishes such as "Bouillabaisse à la Marseillaise" were shown to be more visually appealing, with color enhancing the overall enjoyment of the meal. The role of color in emotional responses to food was later uncovered in research carried out by psychologists studying visual abilities.

The ability to recognize images of prepared food was investigated, and significant variation was found among participants. While general object recognition abilities accounted for some of the differences, it was also determined that individual attitudes toward new foods, known as food neophobia, played a significant role. Those who were more resistant to trying new foods performed worse in tasks related to food recognition.

Further exploration into the role of color in food recognition was prompted by these findings. A debate had emerged over whether color was essential for the brain's response to food. To resolve this, experiments were replicated using grayscale images of food. It was found that while participants made more errors without color, the general pattern of variation in recognition abilities remained the same. Interestingly, the correlation between food neophobia and food recognition disappeared when color was removed, suggesting that color gave adventurous eaters an advantage over picky eaters.

Two components of food recognition ability were proposed: one that operates independently of color and one that is tied to emotional responses influenced by color. A prediction was made that colorblind individuals, particularly men who are more commonly affected by color blindness, might exhibit less food neophobia due to their restricted color perception.

Through recruiting color-blind participants and evaluating their levels of food neophobia, it was confirmed that colorblind men were indeed less prone to food-related anxiety compared to men with normal color vision. A follow-up study also revealed that colorblind men reported lower levels of food disgust. It is believed that their limited perception of color reduces the emotional resistance to unfamiliar foods.

The significance of color in shaping emotional responses to food was reinforced through these findings. Color allows individuals to determine whether food is properly cooked or if produce is fresh. Research has also shown that color can influence the taste of food, and it has been suggested that the coloration of plants and the ability of animals to detect these colors may have co-evolved.

The connection between color and food-related emotions opens the door to addressing severe cases of food neophobia. As further research is conducted on the relationship between color perception and food recognition, targeted interventions could be developed to encourage healthier eating habits. Just as Julia Child’s colorful dishes captivated viewers, understanding the influence of color on food can help enhance both the appreciation and enjoyment of meals.
