Detailed Solution

The above statement is false.
The retina is the part of the eye at the back that contains light-sensitive cells. These specialised cells are known as photoreceptors. Cones are colour sensitive because they are sensitive to bright light, whereas rods are colour sensitive because they are sensitive to dim light. Conversely, cones are more sensitive to one of three different colours (green, red, or blue).
The correct statement would be, cones are sensitive to bright light.
