In the morning, the outside temperature is -12 degrees Celsius, the indigo liquid temperature is 25 to 28 degrees Celsius, and the room temperature of the dyeing place with glass on three sides is 7 degrees Celsius when it is cloudy and 18-20 degrees Celsius in the daytime when it is sunny. There is 1m of snow outside, and icicles and snow dance behind the glass. Milky white woolen cloth from the Occitanie region of France is dyed green by the water-soluble leuco indigo reduced by indigo reducing bacteria. When the cloth is removed from the indigo liquid, it gradually oxidizes with oxygen in the air and turns into indigo, which turns indigo. Color contrast is strong in winter.
