#Retinalstimulation

Imagine being able to perceive a color that no human has ever seen before—a jump in our sensory experience that until now has belonged only to science fiction. This is exactly what a groundbreaking team of engineers, computer scientists, and ophthalmologists at the University of California, Berkeley, in collaboration with experts from the University of Washington, claim to have achieved. In recently published research in the journal Science Advances, these scientists reveal that by precisely targeting specific cells in the human retina, they have enabled volunteers to see a novel color, which the team dubbed “olo” (MedicalXpress).

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.
