Judas Iscariot
Judas Iscariot (died AD) was a disciple and one of the original Twelve Disciples of Jesus Christ. According to all four canonical gospels, Judas betrayed Jesus to the Sanhedrin in the Garden of Gethsemane by kissing him and addressing him as "Rabbi" to reveal his identity to the crowd who had come to arrest him. His name is often used synonymously with betrayal or treason. Judas's epithet "Iscariot" most likely means he came from the village of Kerioth, but this explanation is not universally accepted and many other possibilities have been suggested.
Yellow
During the Post-Classical period, yellow became firmly established as the color of Judas Iscariot, the disciple who betrayed Jesus Christ, even though the Bible never describes his clothing. From this connection, yellow also took on associations with envy, jealousy and duplicity.
