The color reflects in the eyes.

We named the brand color of "dō" as "Juntan" 循丹.
"Jun 循 (using the Chinese character meaning circulation)" means to obey, snuggle up, circulate, comfort, and "tan" 丹 means red, red clay, and the spirit of truth.
The name was given in hope to stay close to the tired hearts of modern people to help them stand up again with their own feet.
