Description
A natural yellow dye obtained from sunflower (Helianthus annuus) blooms. Sunflowers produce a bright yellow dye in alkaline solutions that is not lightfast. In acetic acid solutions, however, sunflowers give a colorfast golden color on wool with an alum mordant. The seeds of the sunflower plant were also used by native Americans to produce a dark purple color used for dyeing baskets.
