Multicolor photochromic materials are highly attractive in high‐end intelligent terminal products for on‐demand information displays. It is extremely challenging to realize multicolor photochromism by constructing multiple F‐centers in a single inorganic host through a traditional trap engineering strategy. Here, a promising design strategy is demonstrated to develop multicolor photochromism via manipulating chemical coloration (CC) in inorganic photochromics. To validate this, the colored BaMgSiO ₄ is synthesized by adding different colorants (Co, Cr, Nd, etc.), displaying both bright chemical color and high photochromic efficiency with fast response speed to sunlight. Upon UV or sunlight irradiation, the photochromic coloration (PC) can effectively composite with CC, then achieving reversible multicolor chromism (deep blue to gray black @Co, dark green to reddish brown @Cr, pale purple to deep purple @Nd, etc …
