For generations, the color blue has eluded the natural food palette — present in the world but rarely in quantities useful to industry. Now, a multinational team of scientists has used computational protein design to coax red cabbage into yielding a stable, vivid cyan-blue colorant, bridging the ancient human desire for food that feels grown rather than made with the molecular precision required to achieve it.

Consumers may benefit from safer, naturally-derived food colorants with potential health advantages over synthetic alternatives. Prices could initially increase during transition, but may stabilize as production scales. Products labeled 'natural' could command premium pricing.
Regulatory bodies (FDA, EFSA) will need to approve the new colorant for food use. This could accelerate phase-out of synthetic dyes like FD&C Blue No. 1 and No. 2. Agricultural subsidies may shift toward red cabbage cultivation. Clean-label and natural ingredient trends could drive stricter regulations on synthetic additives.
