November 15th Color Calendar
Sakuranezu (cherry blossom mouse)
"A color that subtly hints at sadness amidst blessings."
Sakuranezu is a dull cherry blossom color with a pale crimson tint tinged with gray and light ink. This color is known as "sumi-zome cherry blossom" and embodies the sorrowful beauty that originated in waka poetry from the Heian period.
"If the cherry blossoms in the fields of Fukakusa have a heart, let them bloom in ink this year" - a song mourning the death of a loved one, wishing that even the cherry blossoms be enveloped in the color of mourning. This sentiment is permeated into the color "Sakura Nezumi."
November 15th is Shichi-Go-San, a day when children dress up in their finest attire and visit shrines. Amidst the vibrant crimsons and pinks, a hue like cherry gray creates a quiet dignity. It's a color that subtly hints at the transience of life amidst the blessings.
This color is also in line with WABISUKE's philosophy. The serenity that lies within gaiety. The space within joy. Sakura Nezumi is a color that accompanies the turning points of life. It is an appropriate color for days to celebrate children's growth and days to pray for the passing of seasons.
