Some examples of colors gotten from natural dyes.
The yarn is all hand spun and hand dyed. Some of the colors are from natural dyes and others from chemical based dyes.
Generally, natural dyes yield rather muted colors. Brighter colors are most often chemical dyes, though some bright colors (such as the red that comes from adding lime juice to the dye made from the insect cochineal, seen at the very right of the center group of pinks/reds) do come from natural sources.
