Adam is a figure in the Book of Genesis and the first human to appear in the Bible. In the Genesis creation narratives, he was created by Yahweh-Elohim ("Yahweh-God", the god of Israel), and the first woman, Eve (meaning "living") was formed from his rib. One time, he and his wife were persuaded by a snake or serpent and ate the fruit of the tree. As a result, both immediately become aware of the fact that they are naked, and thus cover themselves with garments made of fig leaves (Gen. 3.7). Then, finding God walking in the Garden of Eden, Adam and Eve hide themselves from God's presence (Gen. 3.8). God calls to Adam "Where art thou?" (Gen. 3.9, KJV) and Adam responds "I heard thy voice in the garden, and I was afraid, because I was naked; and I hid myself" (Gen. 3.10, KJV). When God then asks Adam if he had eaten of the tree of the knowledge of good and evil, Adam responds that his wife had told him to (Gen. 3.11-12). (From Wikipedia)
However, in Color Wiki, Adam is a reference to man coming from the dust of the Earth. Ancient tradition used the phrase "dust of the Earth" to refer to red clay. Therefore, Terra Cotta, sand and flesh colors were blended to create the color Adam.
In the picture, Adam is naked and the body is where the color resembles.
