Henna produces yellow to orange, to brown colours depending on the mordants used and other variables.
What are Mordants? - Mordants are metallic or mineral salts which, when added to the natural dye bath either enhance, intensify, or change the colour. They also play a large role in making the resulting shade faster to light and washing. All mordants should be treated with care and common sense. Dyers rarely agree on the quantities of mordant to be used. There are general guides though the best way for any dyer to find the amount of mordant to be used is to conduct their own experiments.
There are many different recipes for using natural dyes and your results will depend on your choice of mordant or what you're dying, we sell both natural dyes and mordants so everything you need is on our website. If you are new to natural dyes you will discover that the process of preparing your natural dyes is as much an art as the finished results. As with anything of this nature it is best to make samples and experiment first.
