We demonstrated the emission of multicolored light from a powder electroluminescent device using a thermochromic material through temperature control. At 20°C, the emission of a sapphire blue light was observed. Upon increasing the temperature, the color of the thermochromic materials changed, leading to sky‐blue emission.
