However, the exact shade can vary depending on:
* Blood flow: A healthy tongue has good blood circulation, making it appear pink.
* Pigmentation: Some people have naturally darker tongues due to melanin.
* Diet and medications: Certain foods (like beets) or medications can temporarily change the tongue's color.
* Health conditions: A white, yellow, or black tongue can be a sign of a medical condition like oral thrush or dehydration.
It's important to note that a change in tongue color can be a sign of a health issue. If you notice any significant or persistent changes in your tongue color, it's best to consult a doctor.
