In aprevious study, the mutual interaction between $Fe_2O_3$ and $TiO_2$ was found to influence the color of celadon glaze. Celadon samples were prepared with varying concentrations of $TiO_2$ at a fixed level of $Fe_2O_3$. The electronic states of Fe and Ti were analyzed by M$ddot{o}$ssbauer spectroscopy and electron spin-resonance spectroscopy, respectively. These results were examined with the celadon colors measured according to CIELAB values. This study revealed that an increase of $Ti^{3+}$ in the glassy phase decreased the $Fe^{2+}/Fe^{3+}$ ratio, resulting in a color change of the celadon samples in the GY and Y groups. The maximum reflectance wavelength was shifted from 505 nm to 610 nm with an increase in the $TiO_2$ concentration.
