Why do colourblind people see colours differently?

Colourblind people see colours differently because they do not have all the necessary information from the L, M and S cones. A simile would be to try to obtain different paint colours by mixing only two primary colours: we would never be able to obtain the full range of existing colours.

When a large quantity of water is observed, as happens in the sea, we notice a blue color that can vary depending on the mass of water we are observing. Professor Inmaculada Pascual Villalobos explains why.
