Why are tongues pink?

Browse → Human Body → Outside the Body
There are a few different reasons that our bodies have different colors.  One of them is because we have special chemicals called pigments. Pigments cause color and can help reflect harmful rays from the Sun.  Most of the skin on our bodies has pigment, which makes it a brownish color.  Some people have more pigment than others.  More pigment means darker skin.  When people's eyes have a lot of pigment they have dark brown eyes.

Another reason our bodies have color is because of the blood under our skin. Some parts of our bodies, like our lips and our tongues, don't have much pigment so it's the blood running through them that gives them color.  In the case of our tongues, the blood that travels through it to fuel its many muscles makes it pink!
