Rods
Alcohol can reduce your ability to distinguish colours, especially red and green.
Black
Iron is mainly responsible for the colour red.
Orange and blue
The colors of fireworks are largely the result of the burning of tiny particles of metallic elements.
Chlorophyll (a, b, c, d, e, f), carotenoids (carotenes, xanthophyll, fucoxanthin), and phycobilins (phycoerytherin, phycocyanin) are the major groups of pigments that are associated with photosynthesis. Plants mostly use chlorophyll a, chlorophyll b, carotenes, and xanthophyll as their photosynthetic pigments.
Cones in the eye contain 3 types of photopigments that are each sensitive to different wavelengths of light (short, medium, long). When light of a specific wavelength stimulates a cone, the corresponding photopigment is activated, sending a signal to the brain that allows us to distinguish different colors.
Cones in our eyes are responsible for color vision and sharp detail. Without cones, we would only see in shades of gray and have poor visual acuity. This would greatly impair our ability to see colors and distinguish fine details in our surroundings.
Allosaurus is only known from fossilized bones, which don't preserve the color of an animal. In fact, we don't know the colors of most extinct animals. However, the fossilized feathers of some small dinosaurs have preserved the structures responsible for color, and by examining these fossils under a microscope, paleontologists can determine the colors of these dinosaurs. A few dinosaurs whose colors have been discovered include Anchiornis, Sinosauropteryx, and Confuciusornis.

Yes, rods are highly sensitive to dim light and low amplitude light waves. They are responsible for our ability to see in low light conditions, but they are not as sensitive to colors as cones are.
