  The first paper in this series explored the effects of altering the chemical
mixture of the stellar population on an element by element basis on stellar
evolutionary tracks and isochrones to the end of the red giant branch. This
paper extends the discussion by incorporating the fully consistent synthetic
stellar spectra with those isochrone models in predicting integrated colors,
Lick indices, and synthetic spectra. Older populations display element ratio
effects in their spectra at higher amplitude than younger populations. In
addition, spectral effects in the photospheres of stars tend to dominate over
effects from isochrone temperatures and lifetimes, but, further, the
isochrone-based effects that are present tend to fall along the age-metallicity
degeneracy vector, while the direct stellar spectral effects usually show
considerable orthogonality.
