keratin through the process of keratinization
Waterproofing requires a compound that is hydrophobic, i.e., "water-avoiding." In chemical terms this means a non-polar compound, because water itself is a polar molecule (having + and - regions). The basic principle is that polar and non-polar molecules generally don't interact. Lipids are mostly non-polar (though the molecule might have a polar end) so they can serve as waterproofing. Wax, for instance, is a lipid.

Keratin is a tough, waterproofing protein. Keratin is secreted by the cells of the epidermis (the outermost layer of skin).
Epidermis is a skin layer with five sublayers. One of its sublayer is the Stratum Granulosum or the Granular layer which secretes the waterproofing glycolipid that controls water loss in the epidermis.

It is the part of a molecule that is responsible for its color. When a molecule absorbs a wavelength of visible light and reflects or transmits others, this is when the molecule's color will appear.
