Human palm skin.

Human palm skin doesn't contain
melanin a skin pigment.
That's the reason for its fair colour.

[And to say a bit more elaborately,
These structures are made of 
keratin, a tough protein. Similar 
types of keratin also make up human 
hair, the scales and claws of reptiles, 
and the feathers, claws, and beaks of 
birds. The palm of the hand doesn't 
contain melanin (skin pigment) or 
hair follicles.]
