"Yellow is one of the most common colours found in nature and an abundance of natural yellow pigments, but yellow dye is also a natural dye that fading off easily. Yellow dyes that are commonly used in Indonesia are turmeric, tegeran wood, jackfruit wood, and mango leaves."
Turmeric
Turmeric is known to be from South Asia (Curcuma aromatica), turmeric was used as a yellow dye by the first Austronesian cultures to settle in the Indonesian Archipelago. Turmeric is one of the brightest and richest producers of all natural dyes. Turmeric can produce a bright yellow-orange colour so it will dye cotton well. However, turmeric has a drawback, because it is at the least light-resistant of all-natural dyes.
Jackfruit
Jackfruit (Artocarpus heterophyllus) is a tree with a straight trunk that can grow to 25 meters tall. Jackfruit grows throughout the archipelago, from Sumatra to Tanimbar, Maluku and Papua. The sapwood or the wood core of the jackfruit produces a relatively stable yellow-orange dye. The colour resulting from the extraction process of jackfruit tree wood chips.
Mango Leaves and Skin
Mango (Mangifera Indica) is a tree that grows in the tropical rain forests of South and Southeast Asia. It can live for several hundred years and can reach a height of 40 meters or more. Mangoes leaves and bark can produce a variety of colours ranging from brown, greenish-brown, grey, and pale brown to yellow depending on the mordant used. The yellow colour can be produced from the extraction of the leaves and bark of the mango tree. Mango tree bark has a higher concentration of mangiferin pigment and tannins than mango leaves. Cotton threads absorb mango leaf dye better than mango tree bark dye.
