Chromoselective activation of redox‐active chemical bonds introduces a new selectivity parameter in visible‐light photoredox catalysis. In their Communication on page 7676 ff., I. Ghosh and B. König show that Rhodamine 6G, an inexpensive commercially available xanthene dye, shows different redox potentials under different colors (blue and green) of visible‐light irradiation. This enables selective photocatalyst activation for sequential bond activations under different light sources.
