The Color Pink
Like green, which signifies life but can also suggest death, red contains its own polarized opposites of meaning and effect. Red is the most violent, aggressive and stimulating color there is, while pink (red’s pale hue) may be the most soothing color of all, inducing feelings of friendliness, tenderness and affection.
Pink is calming, so much so that there’s a color called “Drunk Tank Pink” that’s used to paint the walls of jail cells to calm aggressive prisoners. (The physical effect is real, but temporary.)
