Getting E254: Cannot allocate color

[xkef]

Installed with ./install in fresh macos sierra virtual machine.

Starting vim from iTerm gives the following error:

Error detected while processing function statusline#update_highlight:
line 27:
E254: Cannot allocate color guibg=#a7adba
E254: Cannot allocate color guibg=#a7adba

The color code depends on the color scheme loaded, which here corresponds to the base16-ocean
let g:terminal_color_12 = "#a7adba".

I am using the newest stable iTerm2 where "echo $TERM" gives "xterm-256color".

Unfortunately don't see how. I am not using macvim although a newer version is installed.
I'm a vim newbie but tried to fix it myself.

The error happens in following line of statusline.vim:

let l:bg=synIDattr(synIDtrans(hlID('User2')), 'fg', l:prefix)

Changing 'fg' to 'bg' fixes the error but destroys your nice status line artwork a bit. Is somehow the passing of font properties like italic (pinnacle?) or color messed up? why is this only happening to me?

Okay, got it to work. Deleting the repo, cloning again and manually installing command-t and ycm works for me. Somehow running "./install vim" produces the error.
