Optical metasurfaces consist of 2D arrangements of nanoparticles can control the amplitude, phase, and polarization of an incidence field. Here, based on a developed comprehensive theory to describe the optical response of periodic metasurfaces, we explore the possible color coverage of metasurfaces made from isotropic coreshell particles. The color palette of metasurfaces in transmission and reflection is systematically explored and fundamental limits are investigated. The research bridges the gap between simulation and design by introducing a novel framework that translates desired color and iridescence outcomes into metasurface parameters.
