Eccrine sweat gland
Skin has 250 millions of Eccrine sweat glands and can excrete sweat directly out of skin. The distributions almost are near palms, soles, underarms, and forehead. The excretion will be adjusted by emotion and temperature.
The excretion will start at dermis and open at epidermis.
Apocrine sweet gland
It is larger than eccrine sweat gland and from dermis.
It locates at the underarm, areola and nipples of the breast, ear canal, eyelids, wings of the nostril, perianal region, and some parts of the external genitalia.
The smell of the odor is the interspecific relationships of microorganisms when sweats excrete to the epidermis.

sebaceous gland
They locate at the face and scalp, but also on all parts of the skin except the palms and soles.

They will excrete lipids with cell divisions.

This value is based on CIELab of the CIE system. The CIE has defined a system that classifies color according to the HVS (the human visual system). This system is called color space which is in combination with physical device profiling, it allows for reproducible representations of color, in both   analog   and   digital   representations. A color is thus usually specified using three co-ordinates, or parameters. These parameters describe the position of the color within the color space being used. They do not tell us what the color is, that depends on what color space is being used. There are more than one color spaces for the applications. This is because different color spaces are better for different applications, for
