OSX - sierra
iterm2 3.0.13
tmux 2.3
vim 8.0.176
colors work fine in bare iterm2:
but under tmux:
iterm2:
echo $TERM
xterm-256color
tmux:
echo $TERM
screen-256color
tmux config
vimrc
I'm running out of ideas. and google foo is not helping.
A search for 'tmux vim colors wrong' turned up this answer. Start tmux with the -2 option to force 256 colors.
t_* is needed because these are not set automatically by vim for anything but xterm. But tmux only supports screen-256
:h xterm-true-color
Moving t_8f and t_8b below set termguicolors fixed my problem.
