The properties of the first generation of stars and their supernova (SN)explosions remains unknown due to the lack of their actual observations.Recently many transient surveys are conducted and the feasibility of thedetection of supernovae (SNe) of Pop III stars is growing. In this paper westudy the multicolor light curves for a number of metal-free core-collapse SNmodels (25-100 M$_{\odot}$) to provide the indicators for finding andidentification of first generation SNe. We use mixing-fallback supernovaexplosion models which explain the observed abundance patterns of metal poorstars. Numerical calculations of the multicolor light curves are performedusing multigroup radiation hydrodynamic code STELLA. The calculated lightcurves of metal-free SNe are compared with non-zero metallicity models andseveral observed SNe. We have found that the shock breakout characteristics,the evolution of the photosphere's velocity, the luminosity, the duration andcolor evolution of the plateau - all the SN phases are helpful to estimate theparameters of SN progenitor: the mass, the radius, the explosion energy and themetallicity. We conclude that the multicolor light curves can be potentiallyused to identify first generation SNe in the current (Subaru/HSC) and futuretransient surveys (LSST, JWST). They are also suitable for identification ofthe low-metallicity SNe in the nearby Universe (PTF, Pan-STARRS, Gaia).
