Baker-Miller Pink

Baker-Miller pink, also known as P-618, Schauss pink, or drunk-tank pink, is a specific shade of pink that researcher Alexander Schauss identified in 1978 as reducing hostile, violent, or aggressive behavior in people exposed to it, based on early tests showing lowered heart rate, pulse, and respiration and a period without hostile incidents after a naval correctional facility painted its holding cells the color. Later controlled studies complicated the original claim: a 1987 study found lower anxiety but no effect on grip strength or motor precision, and a 2014 study at Ghent University found pink and gray cells reduced prisoner aggression to the same degree over three days, suggesting the color itself may not be the active ingredient and that the original research may have carried methodological weaknesses.
