Color symbolism has been woven into art, fashion, and branding for millennia. Ancient societies linked blues to serenity, reds to vitality, and greens to growth. Modern psychologists began formalizing these associations in the 20th century, asking whether personal preference for a hue correlates with measurable personality traits.
Over the last decade, researchers have employed large‑scale surveys and implicit association tests to test these hypotheses. While some patterns emerge—such as a tendency for individuals high in openness to favor brighter, more saturated colors—results are often weak, highly context‑dependent, and influenced by culture, age, and situational mood.
