Abstract: Recent large-scale time-series surveys provide us with homogeneous datasets which are useful for investigating systematics of variations of classical Cepheids. Combining our near-infrared (JHKs) catalogue with the OGLE-III optical (VI) counterpart, we here discuss the light curves of classical Cepheids in the Small Magellanic Cloud in these wavelengths. The shapes of the light curves show a systematic trend varying with the wavelength and with the period. These systematic characteristics can be explained by simple arithmetic considering the bolometric correction and underlying variations of temperature and radius of Cepheids.
