Psychopaths may unknowingly reveal their inner turmoil through something as simple as their favorite color.
Researchers have found that people drawn to blue are more likely to struggle with mental illness, including psychopathy and depression.
The connection between color and mental health was first identified in 1961, when a study in the American Journal of Psychology found that over 40 percent of psychiatric patients named blue as their favorite color.
Decades later, modern studies have confirmed these findings. A 2017 study in China discovered that patients with depression gravitated toward cooler shades such as blue and purple, only beginning to favor brighter hues like yellow after undergoing therapy.
But a 2019 paper by George Washington University psychologist Marc Nemiroff, PhD, suggested there may be a darker side to choosing blue.
In Psychology Today, Nemiroff explained that blue is universally loved for its ability to calm the body, lower heart rates and ease stress.
Seeing blue in the sky or ocean provides a safe, stable sensation for those seeking focus, peace, or emotional balance. However, the color can also signal sadness and loneliness, especially among the mentally unstable.
People experiencing anxiety, depression, or a need for control often lean heavily into blue, using it as a mental chill pill.

'Psychologically, blue encompasses a critical aspect in the panorama of human affective life. It represents happiness or joy, as in blue heaven and blue skies. Thus, it lifts the spirit,' Nemiroff wrote.
'And blue is the color of sadness, of pain and hardship, as in singing the Blues. Blue is the harbinger of depression. Emotionally, then, blue is the most accepting of colors, the most inclusive of colors.'
Although research connecting blue to mental health spans decades, the idea recently went viral on social media, with users asking friends and followers to reveal their favorite color.
Multiple studies have suggested that when emotions are in chaos, people crave blue's cool, steady vibe to feel more grounded.
While psychopaths are often described as emotionally numb, new research finds that those displaying traits like impulsivity and lack of empathy are still prone to feeling low.
Even individuals who appear detached and fearless may favor blue because of underlying mental health struggles they're trying to stabilize.
An international team from the US and Asia found that while psychopaths seem calm and detached on the surface, their brains are wired for anxiety and impulsiveness underneath.
That hidden turbulence, combined with darker personality traits, can turn inward, amplifying emotional distress rather than numbing it.

Psychopaths often display what psychologists call the 'Dark Triad' of personality: acting cold, impulsive, and guiltless (psychopathy), being cunning, manipulative, and power-hungry (Machiavellianism) and being self-obsessed or craving admiration (narcissism).
Although these individuals are often seen as robotic and calculating, a February 2025 study in the Journal of Research in Personality found they still suffer from isolation.
'Previous studies indicate that the dark triad is inextricably linked to depressive symptoms,' the researchers wrote.
Those high in psychopathy and Machiavellianism showed higher rates of depressive symptoms, while those exhibiting more narcissism did not.
