Although chemical dyes are used these days, natural dyes including plant-derived dyes such as indigo, safflower, suo (dark red), akane (madder), shikon (lithospermum root used for purple color), and kariyasu (Miscanthus tinctorius), and animal dyes such as enji mushi (cochineal) were used in the past.
現在は化学染料が使われているが、かってはアイ(植物)や紅花、蘇芳、茜、紫根、刈安などの植物染料、臙脂虫などの動物染料のような天然由来の染料を用いていた。
