  We investigate inflationary models leading to density perturbations with a
spectral index $n>1$ (``blue spectra"). These perturbation spectra may be
useful to simultaneously account for both the amount of ultra large-scale power
required to fit cosmic microwave background anisotropies, such as those
measured by COBE, and that required to give bulk motions and structures on the
$\sim 50~h^{-1}$ Mpc scale.
