On the basis of an extensive grid of Cepheid, nonlinear, nonlocal, time-dependent convective models by Bono et al., analytical Period-Color-Luminosity (PLC) relations as a function of chemical composition were evaluated and compared with observations in LMC and SMC. I provide an analysis of PL and PLC residuals and suggestions for disentangling the effects of reddening and metallicity on the Cepheid distance scale.
