Substances to Help Herbs Retain Color

To help herbs retain color, especially when adding color or making existing color last longer, you can consider substances that improve color adhesion or stability.

• For improving color adhesion: Ingredients like ColorFix™ are known to help color attach better and last longer, particularly in hair color applications, by coating the hair strands. While primarily used for hair, the principle of improving color adherence through coating could potentially be explored depending on the specific application of the herbs.
• For long-lasting color: Certain water-soluble colors, such as the HiStain™ range (Black Color HiStain™, Caramel Color HiStain™), are designed for good adhesion and long-lasting results on the skin, suitable for makeup. These types of colorants are formulated to resist fading.
• Natural Colorants: If you are adding color to herbs, natural colorants like Turmeric Extract Curcumin Yellow Color, Spirulina Extract Phycocyanin Blue Color, or Strawberry Natural Water Soluble Color can be used to impart color. While these provide the color itself, their ability to help the herb's natural color stick may vary.

The best approach depends on whether you are trying to preserve the herb's original color or add a new color and make it adhere well.
