I am surprised with the new colour scheme for 3.8 and although the classic 3.7 theme has gone, I would like to set the new “Light” colour scheme as the default for all users, but at the same time, still allow them to change the theme if they wish, in their user profile.

Has anyone managed to come up with a function to set the default for all users? I’ve searched but can find nothing as this is so new, 3.8 codex not fully written.
