Colorful patterns with a black background are realized based on piecewise reflection tuning of cholesteric liquid crystals induced by a newly designed photoresponsive tristable chiral switch. In article number 1704941 , Yanlei Yu and co‐workers find that the three stable configurations of the chiral switch endow the system with two continuous and adjacent tuning periods of the reflection, covering not only the entire visible spectrum, but also a further wide period within near‐infrared region.
