Natural Colorant Rainbow Cold Process Soap

There was a time in my childhood, I was really into rainbows and collected anything I could that had rainbows.  Even as an adult I love to see a rainbow in the sky, especially if it was a double.  If you would love to create a rainbow layer cold process soap, The Soap Queen has a post called Natural Colorant Rainbow Cold Soap that uses natural colorants to achieve vivid hues of every color of the rainbow.
