Same berry. Same color dose.

Same berry. Same color dose. The caffeinated can pours deeper and holds its color longer. The caffeine isn't coloring anything. It's standing guard.

Here's the chemistry. Berry reds are anthocyanins, and at sparkling-drink pH they live one water molecule away from going colorless. Caffeine is flat, and it stacks on top of the pigment like a lid, blocking that water. Chemists call it copigmentation. The payoff is a deeper, slightly more magenta red that survives the shelf better.

Carbonation helps. The CO2 nudges pH into the sweet spot and purges the oxygen that fades color on its own.

Three catches. It only works on anthocyanins, so beet and paprika drinks get nothing. Purified caffeine at 98 percent or better keeps tea and guarana browns out of a pastel. And caffeine plus tannin-heavy extracts can haze when cold.

That's what DyeConverter™ predicts before the bench does: which ingredients in the deck are villains and which are bodyguards. Real dyes from real suppliers, and the interactions mapped.
