Anthocyanin is the pigment that gives red cabbage its color. When it reacts with iron, tin, or aluminum ions in nonstainless metal knives, it can create off-colors. The other pigment options (flavonoid, anthoxanthin, betalain) are not as commonly found in red cabbage or are not as reactive with metal ions.
