Human wavelength discrimination of monochromatic light explained by optimal wavelength decoding of light of unknown intensity.

We show that human ability to discriminate the wavelength of monochromatic light can be understood as maximum likelihood decoding of the cone absorptions, with a signal processing efficiency that is independent of the wavelength. This work is built on the framework of ideal observer analysis of visu...
