Three: Red, Green, and Blue cones.
All 5.
Cone cells in the retina of the eye detect color. There are three types of cone cells. Two of them detect light of different wavelengths, one medium and the other long. And the third detects the overall intensity of the light source. Your brain uses this information to interpret the combination of those three receptors to give you the sensation that you percieve different colors.
The tongue's receptors are taste buds. They are specialized to detect flavors, and are divided into two types, sweet and bitter receptors. They can detect perceptions of flavors in five types; salty, sweet, bitter, sour, and umani (savory).
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.
Pain receptors.
There are five elements of taste buds: salty, sour, bitter, sweet, and umami.
You have rod cells and cone cells as receptors in your eye. Rods are for intensity of the light. Cone cells are for color vision.
There are not tow types of sensory receptors in the skin there are many types of sensory receptors in the skin i.e., in the CUTANEOUS RECEPTORS of the MECHANORECEPTORS. They are the: Meissner's corpuscles, Merkel's disc, Paccinian corpuscles, Ruffini's end organs, Free Nerve Endings and Hari Follicel Organs.

Two types, nicotinic and muscarinic

Cones are light receptors in the eyes that allow us to see different colors.
5-HT receptors are the receptors for serotonin. They are located on the cell membrane of nerve cells and other cell types in animals.
If you mean types, There are 4 Stratovolcano Cinder cone Shield Dome

The colour receptors in your eye are not monochromatic narrow filters. Each of the three types of cone receptor have some overlap with each other. Rather as three 'bell' curves. Thus a band of light may well excite a response in each of the three types of cone. A human eye may discriminate up to about 10 000 000 colours.
