The relationships between the temperature and the color changes of ther-mochromic materials were investigated using a spectrometer and TV camera. Samples in sheet form have reversible reaction about color changes. From spec-tra, it was found that strong absorbent bands were related to sample colors which were red, green and blue. Intensities of these absorption were varied by temperature changes. Samples showed same characteristics about correlations between brightness and the temperature, especially histeresis. It was clarified temperature profile can be measured by these thermochromic materials.
