This retina processing model has long served as the mainstream scientific template for human color vision research and has also proven to be useful for the practical design of display technologies, user interfaces, and medical diagnosis tools that enlist human color perception behaviors. You would not flunk the Ishihara. Functional tetrachromats (1 in millions of people) see much wider ranges of colors than normal trichromats, and they pass Ishihara with ease. Normal vision people have three types of neural signals going to their visual cortex - white/black, red/green and blue/yellow. Tetrachromacy.
