I apologize for the mistake in my previous response. The correct answer is:
True
what is the real answer
The correct answer is True.
Cones detect light and are responsible for detecting color vision. There are three types of cones that detect different wavelengths of light - red, green, and blue.
Rods are responsible for detecting dim light and are not involved in color vision.
The brain combines the signals from the cones to interpret and perceive color.
