Sejong pen nib in red, the Joseon king's 'jucheol' color
Director Park Jong-jin explained, "The Sejong pen's nib color is red. It's the color of the Joseon kings. Not just plain red, it's jucheol. It's a slightly heavy, dark red." This is not simple red but a weighty, deep red meant to express the dignity of the Joseon royal court.
