Because the pigment melanin which determines the depth of colour in skin hair and eyes, is less present in these areas inc the mouth soles of feet etc. It's probably also related to the fact that these are areas where there are fewer hairs and no subcutaneous (deep) tissue so less light is absorbed.

I am going to have a guess here and say that the pigmentation on the outer surface of the skin deflects the sun's rays and stop them from being overheated and burned,and the skin is thinner,but the skin on their palms are thicker and is less likely to burn.

Probably for the same reason that I (a Scando-Euro-Mutt) have palms much lighter than the backs of my hands. look up melanin and sunlight.

Maybe you can ask God one day.
Haven't you noticed this about the
Black Race?
Blacks usually have lighter palms and
soles of the feet.
It doesn't have anything to do with light,
or hair, that's the way the Race was Created.

because like the soles of their feet the palms of the hands aren't exposed to the sun as much

What has this got to do with zoology, which is the study of animals? What are you implying? This should be under anthropology, under PEOPLE.

The same reason when we get a tan our feet and hands stay pale
