  We present here the c-o colors for identified Flora, Vesta, Nysa-Polana,
Themis, and Koronis family members within the historic data set (2015-2018) of
the Asteroid Terrestrial-impact Last Alert System (ATLAS). The Themis and
Koronis families are known to be relatively pure C- and S-type Bus-DeMeo
taxonomic families, respectively, and the extracted color data from the ATLAS
broadband c- and o-filters of these two families is used to demonstrate that
the ATLAS c-o color is a sufficient parameter to distinguish between the C- and
S-type taxonomies. The Vesta and Nysa-Polana families are known to display a
mixture of taxonomies possibly due to Vesta's differentiated parent body origin
and Nysa-Polana actually consisting of two nested families with differing
taxonomies. Our data show that the Flora family also displays a large degree of
taxonomic mixing and the data reveal a substantial H-magnitude dependence on
color. We propose and exclude several interpretations for the observed
taxonomic mix. Additionally, we extract rotation periods of all of the targets
reported here and find good agreement with targets that have previously
reported periods.
