How to Naturally Color Handmade Soap
A comprehensive list of ingredients for naturally coloring soap
Natural soapmaking is an exciting craft that anyone can do from the comfort of their own kitchen. Using oils, essential oils, and the extracts of plants, flowers, minerals, and spices, you can be on your way to creating beautifully scented and colored soap for yourself and loved ones.
This post lists many of the extracts you can use to create vibrant colors in your soap without the need for artificial compounds. Many might be in your kitchen cupboard or growing in your garden already. For those new to making soap, please have a look through my four-part soapmaking series listed below to learn how you can get started.

Listed below are various ingredients that you can use to naturally colour your soap. Categories are based on final colour and the INCI and brief notes are listed beside each listing. Some I have used and have a lot of experience with and some are ideas I’ve found mentioned elsewhere. Unless otherwise stated, the maximum amount you should use in your soaps is 5%.
Basic instructions on how to use the ingredient in soapmaking:
Add to liquid oils – mix with your liquid oils before pouring them into your melted hard oils.
Add at trace – add the natural colouring ingredient after the oils and lye-water in your recipe are mixed together.
Infuse (Macerate) with oils – add the material to oils that are liquid at room temperature and either allow them to infuse for two to four weeks in that way or heat gently in until the colour has been released into the oils. If you’re choosing the longer and room temperature method, make sure to shake your container everyday.
Puree– add at a light trace
Water infusion – infuse the material into water and use the infusion to mix into your dried lye
