An 'ecological valence theory' (EVT) has been suggested to explain why people have preferences for different colors.
Color perception of children 3–5 years of age is an indicator of their developmental stage.
Often societal influences will have a direct impact on what colors are favored and disdained.
From a recent study, it was discussed that associative learning is the process where an individual develops color preferences.
In China, red indicates luck, while in Nigeria and Germany it means the exact opposite.
