Olo is an imaginary color that can only be seen using specialized tools that exclusively activate the M cone cells on the retina. It is impossible to view olo under normal viewing conditions, due to the overlapping sensitivities of M cone cells and S and L cone cells in all wavelengths of visible light that evoke them.
