Lichen dyes are natural colorants derived from various species of lichen, a symbiotic organism made up of fungi and algae. These dyes have been used for centuries in textile and craft applications, providing a range of colors from muted earth tones to vibrant hues. The dyeing process typically involves boiling the lichen in water to extract the pigments, which can then be applied to fabrics or fibers. Lichen dyes are valued for their eco-friendliness and sustainability, as they are sourced from renewable resources. Additionally, they are often used in natural dyeing practices, appealing to those interested in environmentally conscious crafting and traditional dyeing techniques.
