Loading vim-one resets background light #21

Somehow loading vim-one, specifically executing hi Normal ... inside the script, resets background light even if I set it dark.

Below I describe the method to reproduce this problem.

8 directories, 15 files

In init.vim, I put the following:

set tgc  " This line is not necessary for reproduction 
call plug#begin('~/.config/nvim/plugged')
Plug 'rakr/vim-one'
call plug#end()
set bg=dark
colo one

Then I added some debug messages to color/one.vim:
