Colorverse Gyeyu Jeongnan from the Kingdom collection is a pale grey ink with red shimmer. It dries in 20 seconds in a medium nib on Rhodia and has a dry flow. Colorverse ink is made in Korea.

As the second story of the Kingdom series, the first iteration captured the six king's dynasty of Cho-Sun who made great achievements, while the four colors capture the story of a tyrant king's and the dark side of the Cho-Sun Dynasty in Korea.

"Gyeyu jeongnan" refers to a case in which the seventh king (Sejo) of Cho-Sun seized power through murder for the throne. Inspired by this incident, it combined cold gray with red glistening to express a cold and cruel period.
