title: Photographing the synergy between magnetic and colour properties in spin crossover material [Fe(NH2trz)3](BF4)2: a temperature sensor perspective.
abstract: We introduce the first method for imaging colour changes related to a spin crossover phenomenon induced by thermal variation which can be determined with the naked eye or with a photographic digital camera in a solid phase sensor.
