According to the trichromatic theory of colour vision,humans have three different cone receptors,and yet we can detect about seven million different colours.Which of the following is the best explanation of this?
A) Each cone type is responsible for detecting many different colours.
B) Top-down processing (i.e. knowing the colour of specific objects) contributes to our perception of colours.
C) It is the combination of the signals produced by the cones that allows us to perceive so many colours.
D) The light wavelengths are perceived as different shades depending on the strength of the wavelengths.

The trichromatic theory suggests that humans have three types of cone receptors that respond to different wavelengths of light (short, medium, and long). However, the perception of millions of color variations is possible due to the combination of signals produced by these three cones. The brain then interprets these combined signals to produce a wide range of perceived colors. Therefore, option C is the best explanation for this phenomenon.
