Putty + vim == uneven background

After manually installing solarized for Putty, loading the reg, and installing solarized vim manually (placing solarized.vim into ~/.vim/colors/ and specifying solarized as my theme), I'm still seeing background mismatches. It's looking like my default "bold" background is slightly different than the other bold background?

contents of .vimrc:

set nocompatible
set number
set ruler
set linebreak
set scrolloff=3
set et
set ai
set sw=4
set ts=4
set softtabstop=4
set si
set is
set ic
set sm
set sta
set background=dark
set wrap
set textwidth=150
set mouse=a
