Graphics, Illustration and Visual Communication Design Irozuki Calendar by Takafumi Miki Irozuki is a calendar that is changing the color every month and having an enjoyable mood like an interior. As the seconds tick away and every season’s transition, the calendar lives with you through the year. You can enjoy the different colors every month after bringing a piece of the calendar to the back. 6 months later, another color combination will appear for you. Designers could make this changing point by using only 6 papers for 12 months. They wish to bring color to every one of the users' lives.
