response: Well, I know that gold  and skin color was represented using orpiment and ochre pigments in Egyptian tombs
original_response: I read that yellow or gold was used on Egyptian tombs for skin color.
history: how do I eradicate the color yellow from existence?? i hate it! I am not sure if that is posible. But speaking of yellow, did you know that it is actually used to create other colors in the RGB model? I had no idea about it. I wonder how yellow has been used throughout history
knowledge: Ochre and orpiment pigments were used to represent gold and skin color in Egyptian tombs, then in the murals in Roman villas.
