I came across this in an article about plants used for dyes and could not find out what it was. Duobot gives the pastel shade but does any one know? It gives blue.
I know "pastel" is a plant used in dying blue textiles. My dictionary calls it "woad" in English... who knew??
The only meaning I know for pastel is indeed the color shade named "pastel". I didn't know it was a plant.
