The Chemistry Behind It
Anthocyanins are plant pigments with special ring structures that change shape when exposed to acids or bases—causing dramatic color shifts from red to purple to blue!
C
Carbon (C)
Forms the complex ring structures in anthocyanin molecules
O
Oxygen (O)
Accepts and donates protons (H+) during pH color changes
H
Hydrogen (H)
pH is literally "potential of hydrogen"—H+ ions cause color shifts
