Rod cells are sensitive to light due to chemical reactions that pass through cellular membranes, stimulating electric nerve impulses that your brain then forms images with.
An interesting experience to this is easy to do. It is call after image, image reversal, and many other things. But if the chemical reaction continues for a while, it takes the cells a while to recover, maybe 20 or more seconds.
To experience this, cut out a square or round circle with black paper. Glue it onto the middle of a white sheet. Next hold this paper in front of your eyes, with a bright light shining on it of course, for a minute or so. Do not move your focus from the image on the paper or look around or the experience will not work well.
Then shut your eyes tightly and maybe even place your hands over your eyes. You will see the reverse image now for a few seconds. You can experiment with this using different colors, or even look at a window on a bright day. Close your eyes, and you still will have a few seconds of the image.
Rhodopsin
There are light-sensitive visual pigments .
Rods, which perceive black and white and gray, and cones, which perceive color.
The retina has two kinds of light sensitive cells, called photoreceptors, the rod and the cone cells. Rod cells are sensitive to absolute light levels (not color vision) while cone cells are used for color vision.
Rods respond to very low levels of light and are primarily responsible for night vision.They also:A Rod Cell is a type of light-sensitive nerve cell found in the retina.Rod cells do not process fine details or colour differences but are highly sensitive to light. A single photon of light is all that is require to produce a response from a Rod Cell.Loss Rod Cells can result in the condition known as Night Blindness.

Rod cells are sensitive to dim light, while cone cells help you see colors.
Rods are for seeing light and dark, cones are for seeing color.

There are two types of photoreceptors in the retina, cone cells and rod cells. There are 92 million rod cells in a retina. Rod cells function in less intense light and are important for peripheral vision and night vision.
The rods in the retina of the eyes are sensitive to low levels of light and movement. The cones are the ones that are sensitive to color and intensity, so the rods do not see color.
Colors do not exist without light. Your eyes have rod cells and cone cells and only the cone cells can perceive color. However, in low light areas only rod cells are sensitive enough to be activated and they cannot perceive colour. This is a physiological interpretation to the question as color, as far as we know, is an animal perception to the differences in the frequency of light and may not be a universal perception.
Rod cells are excited by very low levels of light, in contrast to cone cells that are excited by higher levels of light.
