Mix five pigments to match a traditional Japanese color each day. Your colors slowly dye the creature of the month into a one-of-a-kind keepsake.
Choose from five pigments to mix and match a traditional Japanese color each day.
Hitoiro is a hands-on color craft that takes just a few minutes. Make a color, see how closely it matches, and slowly dye the creature of the month. No art or paint experience is needed.
YOUR COLOR OF THE DAY
A color tied to Japan's seasonal almanac and 72 microseasons arrives each morning. Read its name and story, choose pigments from the palette, drop them into a dish, and stir with your finger.
Before your brushstroke, you can add more pigment and stir again to adjust the color, or use Rinse the dish to start the mix over. Compare your paint with the target by eye. When you're ready, lay down one brushstroke and let it dry to see your matching score. You get one scored result per day.
ONE MONTH, ONE CREATURE
Every color you make dyes one part of the month's creature. The colors build with the season until a one-of-a-kind creature comes to rest on your folding screen.
Your Book keeps each day's color sample and result. Days you miss remain blank—because the blank space is part of your month too.
MIX FREELY IN ZEN
Explore subtractive color mixing without scores or goals. It is a quiet place for mindful play with color, like a short meditation.
