Caroline Courtois founded “Couleurs du Temps” in 2017 to preserve an ancient know-how in plant dyeing. This textile designer is specialized in silk scarves dying. Once they are woven by the Chambutaires’ silk factory in Chazelles-sur-Lyon, she dyes with natural and solar dyes, mainly made from biowaste such as dried flowers or onion peels. Her technique consists in dyeing the textile in a jar exposed to daylight from sunrise to sunset. Thus, the silk scarf captures a color that reflects the sunlight of the day it was dyed. At the end of the month, a color chart allows her to customize each scarf to the color of the chosen date.
