Natural Plant Dye Price List

1 Kg of dye can dye 2 Kg of fiber (4lbs) in deep shades, 10 Kg (22lbs) in medium shades and up to 20 Kg (44lbs) in light shades. Blood Red is very concentrated and can dye about double this amount.

Blue Castle natural dyes are imported from India where there is an extremely rich and ancient history in the knowledge and craftsmanship of natural dyes. They are produced using a traditional fermentation method giving outstanding wash, color and lightfastness. The dyes are fair trade and because gathering plant material is so labour intensive, it employs many rural woman who are able to supplement their incomes. They are easy to use and environmentally friendly. We also carry a very good herbal mordant although any other type of mordant can also be used. While Blue Castle Fiber Arts tends to focus on the handcrafter, these dyes are also designed to be used and incorporated into the textile industry.

For the home hobbyist or small craft business, the Natural Dye Kit is perfect for trying out the dyes. They work beautifully with natural fibers, particularly wool and silk. Except for the indigo based Navy Blue, Forest Green and Desert Black and Blackberry, these dyes will also work with cellulose fibers like cotton and hemp but will dye in lighter shades.

Indigo with cellulose fiber requires the indigo vat method. We now also stock pure powdered natural indigo but not the other chemicals and supplies required for the indigo vat. (See for supplies and instructions.)

Go to the Blue Castle Natural Dyes Instruction Page to see what is involved in the dye process as well as what other supplies you might need.

Natural dyers are familiar with plant names like madder & indigo. Blue Castle natural dyes are made up of many of the common dye plants but because most of the colors are combinations of various plants they have been given more descriptive names to identify them. For example, Blood Red is a combination of Madder and Soapnut and Mango Yellow is Tumeric and Pomegranate.

There are many colors and shades that can be created with these 12 easy-to-use natural plant dye powders depending on the concentration of the dye bath, the type of mordant and the type of fiber being used.

* Note regarding Navy Blue, Forest Green and Desert Black: these three dyes are a little different from the rest. Because they include indigo in a form that does not adhere to cellulose, they unfortunately cannot be used on fibers such as cotton or hemp which do require the regular indigo vat method.
