Purple isn’t just a color in Thailand’s parks, temples, and markets. It appears in lotus blooms, in fruit stalls stacked with mangosteens, and in the ceremonial robes of monks. Yet cutting-edge neuroscience and art history are prompting a rethink: is purple really a property of the world, or a construct of human perception? New findings suggest purple may be less tangible than we assume, challenging how Thai readers understand color, art, and daily life.

Purple blooms in Thailand’s parks and markets—from the delicate dok bua (lotus flowers) that decorate temple altars to vibrant mangosteens stacked in fruit stalls. Yet behind its abundant physical presence, cutting-edge neuroscience research is challenging what we think we know about purple itself. Is it possible that the color so cherished in art, fashion, and Buddhist symbolism is really an invention of the human brain? Recent findings, highlighted by neuroscientists and art historians, reveal that purple may be less concrete in nature than it appears, calling into question not only the color’s existence, but the very essence of how Thai people (and all humans) experience the world of color.
