Publication process

 At first, I wanted to express the theme of "yellow" more, so I put in a newspaper with racist articles. Also, I wanted to put yellow plastic paper that expressed colored glasses between the books. The book cover got an idea from a painting game that was often played in art class in Korea when I was young. After painting the entire white paper with yellow crayons, paint the black crayons again on top of it - use a pointed tool to scratch the painted black paper, yellow appears. Aren't we looking at people wearing colored glasses without even trying to know what's underneath the yellow?
