#IteachChem 🥽 Chemistry and art: Students are investigating the effect of pH on dye color. I’m obsessed with the bright orange from annatto seeds!

An array of dyed fabric swatches show color differences at neutral, low, and high pH ranges. Dye sources include cochineal, turmeric, madder, annatto, purple corn, and red cabbage.
