From: Food color is in the eye of the beholder: the role of human trichromatic vision in food evaluation
Partial regression plots for food items (n = 253).
Values on the axis are unstandardized residuals. Units are intensity for color brightness on the x-axis and arbitrary values for arousal and perceived calorie content on the y-axis. Three stars mark a correlation significant at p < 0.005, two stars at p < 0.02, and one at p = 0.05. Top panels: scatterplots of the relationship between Arousal and red brightness (left) and green brightness (right) marginalized for all other regressors. Bottom panels: scatterplots of the relationship between Perceived Calorie Content and red brightness (left) and green brightness (right) marginalized for all other regressors.
