We examine the reddening distributions across the Large and Small Magellanic Clouds determined through Classical Cepheids (CCs) from the data provided by OGLE IV. The photometric data for Fundamental mode (FU) and First Overtone (FO) mode CCs in LMC and FO and FU CCs for SMC have been analyzed for their period-luminosity (P-L) relations. By comparing P-L relations with the known distance modulus of these two galaxies, we determine reddening in each of these regions namely E(V-I)
and equivalent reddening values of E(B-V). With the help of these reddening values in different regions, reddening maps in both dwarf galaxies are drawn. From the distribution of individual reddening values
across different regions in the LMC and SMC, an overall mean reddening value is also estimated.
