response: I am not sure about that, but I know that the pope was associated with the color yellow in early christian church
original_response: I am not sure but ochre and orpiment pigments were used in Egyptian and Roman times.  The Pope used the color to represent goden keys of the Kingdom.
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 Well, I know that gold  and skin color was represented using orpiment and ochre pigments in Egyptian tombs I knew yellow was creepy! I bet it represents all sorts of depressing stuff for cultures all over the world! I also read that it was used on a painting in a cave in France that is over 17000 years old!  It was the color of a horse! alright well horses are cool. maybe yellow isn't so bad. who invented yellow?
knowledge: In the early Christian church, yellow was the color associated with the Pope and the golden keys of the Kingdom, but was also associated with Judas Iscariot and was used to mark heretics.
