Pomegranate natural dye extract is a substantive dye, meaning it does not need a mordant to attach itself to the fabrics and be light- and wash fast. However, the use of mordants can give an interesting play of hues. Used traditionally with curcuma for golden yellows in Persian carpets, known in India as Annar.

Main dye compound: Ellagic tannins, Granatonine 
CI Natural Yellow 24

Shading tips:

• No mordant  warm golden yellows (already tannin-rich)
• Alum  brighter, clearer yellows
• Tannin + alum  deeper golden ochres
• Iron (post-mordant, ~1%)  moss greens → black
• Copper (5%)  antique greenish-yellows
• Overdye with indigo  sage to forest greens
• Low temperatures  keep the shade yellow
• Longer dye bath time  shifts yellows toward browns
