This paper looks at how the the ozone, skin structure and sunburns affect complexion and pigmentation. A complex description of skin color based on the analysis of reflected light is presented in the paper. The writer warns that maps of geographical distribution of skin color should be interpreted with caution.

From the Paper:

"Sunburn ranges from mild discoloration to extreme blistering, depending on the time length and circumstances of exposure of UV light, and also the racial and individual characteristics of the person should be taken into consideration. The three basic responses are erythema, hyperplasia, and tanning. Erythema, the reddening of the skin, tends to appears a short time after a mild dose of erythemal sunlight and eventually fades away. The redden results from dilation of blood vessels in the dermis, which are reached by very little UV light."
