Interpreting the color-magnitude diagrams (CMDs) of dwarf galaxies with resolved stellar populations is a tool to study their star formation histories over the last Gyrs. We present preliminary results of chemical evolution models for dwarf irregulars and BCDs with star formation histories inferred by comparing synthetic CMDs with HST optical and near infrared photometry. Particular attention is paid to the interpretation of the CNO abundance patterns.
