Seeing Beyond the Rainbow: Advanced Retinal Stimulation Enables a Brand-New Color
A team of engineers, computer scientists, and ophthalmologists from UC Berkeley, in collaboration with researchers from the University of Washington, reports a groundbreaking advance in human vision. In new research published in Science Advances, volunteers were able to perceive a color not found in the traditional spectrum. The researchers describe this color as “olo,” achieved by precisely stimulating specific cells in the retina.
For Thai readers, the idea of a completely unprecedented color sparks both scientific curiosity and cultural imagination. Color shapes art, design, and ritual—think of color significance in Thai traditions, or the way colors are used in temples and festivals. The possibility of expanding the human color palette could influence Thai textiles, temple murals, and even symbolic representations in religious practices.
