Kojikairo — the birthday color of November 2. Color words: "If you were born on November 2, your color Kojikairo reads as open-hearted and sociable, with a spark that lifts the room. Its color words point to the right hour: you read when effort has ripened, and hand it over at its best. In print, this color shows a modest saturation that settles gently. Colors propose; they do not decide. Your own reading is the final one." #birthdaycolor
