A team of scientists in California say they have discovered a new color they named olo, but you can't see the "most intense teal" with the naked eye.

Each participant had three cone cells “S,” “L” and “M,” which are sensitive to wavelengths of blue, red and green. Using a laser to stimulate M cone cells, which are sensitive to wavelengths of green, participants were said to have seen a color that had not been seen in natural vision.
