  It has been reported that the extinction law for Type Ia Supernovae (SNe Ia)
may be different from the one in the Milky Way, but the intrinsic color of SNe
Ia and the dust extinction are observationally mixed. In this study, we examine
photometric properties of SNe Ia in the nearby universe ($z \lesssim 0.04$) to
investigate the SN Ia intrinsic color and the dust extinction. We focus on the
Branch spectroscopic classification of 34 SNe Ia and morphological types of
host galaxies. We carefully study their distribution of peak colors on the
$B-V$, $V-R$ color-color diagram, as well as the color excess and absolute
magnitude deviation from the stretch-color relation of the bluest SNe Ia. We
find that SNe Ia which show the reddest color occur in early-type spirals and
the trend holds when divided into Branch sub-types. The dust extinction becomes
close to the Milky-Way like extinction if we exclude some peculiar red Broad
Line (BL) sub-type SNe Ia. Furthermore, two of these red BLs occur in
elliptical galaxies, less-dusty environment, suggesting intrinsic color
diversity in BL sub-type SNe Ia.
