Alto theme

Alto is a medium contrast colour scheme developed with the intention of appearing neutral, though not without a personality of its own. It comes in light and dark variants, while using a single 16-colour palette.

Packages or ports of it are available for Vim and Atom, as well as the Xfce4, RXVT-Unicode (urxvt), and XTERM terminal emulators.
