  The nature of the starburst phenomenon in galaxies is investigated using a
narrow band color system designed to study color evolution in distant clusters.
Work on zero redshift, luminous far-IR galaxies, calibrated by starburst
models, demonstrates the usefulness of this color system in isolating starburst
from normal star-forming colors, and also demonstrates a strong correlation
with far-IR colors despite reddening effects. The same color system applied to
distant clusters finds that a majority of the faint blue cluster population are
starburst dwarf galaxies, probably the progenitor of the current population of
dwarf ellipticals in nearby clusters.
