3 types of cones: short (S), middle (M), and long (L) wavelength sensitive.
(S): 430 nm = blue
(M): 530 nm = green
(L): 560 nm = red
Short wavelengths causes the green receptor to fire.
As the wavelength gets longer and closer to 580 nm the red begins to fire, surpassing the green.
Get mix of wavelengths.
Therefore, color vision is the consequence of unequal stimulation of the 3 types of cones. In a specific ratio.
