The first paper in this series explored the effects of altering the chemicalmixture of the stellar population on an element by element basis on stellarevolutionary tracks and isochrones to the end of the red giant branch. Thispaper extends the discussion by incorporating the fully consistent syntheticstellar spectra with those isochrone models in predicting integrated colors,Lick indices, and synthetic spectra. Older populations display element ratioeffects in their spectra at higher amplitude than younger populations. Inaddition, spectral effects in the photospheres of stars tend to dominate overeffects from isochrone temperatures and lifetimes, but, further, theisochrone-based effects that are present tend to fall along the age-metallicitydegeneracy vector, while the direct stellar spectral effects usually showconsiderable orthogonality.
