The skin on the palms and soles has 5 layers compared to skin elsewhere which has 4 layers.
The extra layer is called the Stratum Lucidum.
It's responsible for giving the yellowish/mocha color of the palms and soles of black people and also responsible for the roughness of the palms and soles.
Because of the thickness and carotene deposits of the stratum lucidum, the secreted melanin can't really be seen as well through the stratum corneum. Some (melanin) does it make through which is why lightness between the palms and soles varies with how dark an individual is.
Since fairer people have less melanin, their palms and soles look much paler.
I hope it help you..
