I am trying to use this colorscheme and some highlight groups are identical to the background - not sure why. my TERM is xterm-256color. Tried it in sakura, konsole, and wezterm; with and without tmux - same results.
I have used vim -u NONE to start. then set nocompatible, and syntax on. Then set colorscheme to humanoid. Still seeing the same issue.
Tried changing the background to dark/light. keywords are still the same color as background.
