Dyes

Traditional colors for Central Javanese batik were made from natural ingredients and consisted primarily of beige, blue, brown and black.

The oldest color that was used in traditional batik making was blue. The color was made from the leaves of the Indigo plant. The leaves were mixed with molasses sugar and lime and left to stand overnight. Sometimes sap from the Tinggi tree was added to act as a fixing agent. Lighter blue was achieved by leaving the cloth in the dye bath for short periods of time. For darker colors, the cloth would be left in the dye bath for days and may have been submerged up to 8 - 10 times a day. In traditional batik, the second color applied was a brown color called soga. The color could range from light yellow to a dark brown. The dye came from the bark of the Soga tree. Another color that was traditionally used was a dark red color called mengkuda. This dye was created from the leaves of the Morinda Citrifolia.

The final hue depended on how long the cloth was soaked in the dye bath and how often it was dipped. Skilled artisans can create many variations of these traditional colors. Aside from blue, green would be achieved by mixing blue with yellow; purple was obtained by mixing blue and red. The soga brown color mixed with indigo would produce a dark blue-black color.
