That is correct! I'm using sellout's Solarized color theme for Emacs[0]. It's also available in the Marmalade[1] repository under "color-theme-solarized".

For me it conflicts with the Gnome Terminal Solarized theme though. I had to switch to GTK Emacs (from emacs -nw) to get the color scheme to work. But it looks fantastic now :)
