A drastic color transition from green to brownish‐red in the CuMo 1–x W x O 4 system occurs during a first‐order phase transition. This study shows that it is possible to control this transition in terms of temperature or pressure with respect to the tungsten content (see figure). Hence, the use of these compounds for new applications as temperature indicators or shock detectors is feasible.
