  We combine data from SDSS and the GALEX and Spitzer observatories to create a
sample of galaxies observed homogeneously from the UV to the Far-IR. This
sample, consisting of ~460 galaxies observed spectroscopically by SDSS provides
a multiwavelength (0.15-24 micron) view of obscured and unobscured star
formation in nearby (z<0.3) galaxies with SFRs ranging from 0.01 to 100
M_solar/yr. We calculate a robust dust measure from the infrared to UV ratio
(IRX) and explore the influence of star formation history (SFH) on the dust-UV
color relation (i.e. the IRX-beta relation). We find that the UV colors of
galaxies are only weakly dependent on their SFH as measured by the 4000A break.
However, we find that the contributions of dust and SFH are distinguishable
when colors at widely separated wavelengths (e.g. 0.23-3.6 micron) are
introduced. We show this explicitly by recasting the IRX-beta relation as a
more general IRX-SFH-color relation, which we examine in different projections.
We also determine simple fits to this relation.
