Color change is common in nature and often signifies a seasonal transition, such as from summer to autumn. In their Communication on page 12799 ff., S. Huan, Y. Li, and co‐workers report a new colorimetric detection method that takes advantage of an old technology. The design makes use of a DNAzyme, urease, and magnetic beads to translate the presence of E. coli bacteria into an increase in the pH value, thereby enabling colorimetric detection using the litmus test.
