Baade–Wesselink radii derived using VJHK photometry are used to test the metallicity dependence of the Cepheid P–L relation using three collections of metallicity estimates from the literature. The hypothesis that Cepheids at the LMC metallicity ([Fe/H] ~ −0.2) could be several tenths of a magnitude fainter than at solar metallicity is not supported by the evidence.
