The same grey colors

[krnl0138]

I installed plugin via Plug as usual, functions are working properly, but every time I see the same greyish color output, despite all changes in options it stays the same.
No difference in vim and neovim.

What did I do wrong?

Neovim 0.3.4-2
gvim 8.1.0996-1

This plugin works using guifg. If you're working on a terminal, you have to use a terminal that supports true color and you also need to set termguicolors.

I think the author could make this clearer in the documentation, but that's about it, I'm pretty happy with the results myself:

@fer22f is correct, you need :h termguicolors to be on. My bad for not documenting anywhere, I'll add it to README and docs.

Going to reopen this so that if anyone else has this issue they can see the comments.

My two cents
I use vim inside tmux with base16 shell
Enabling termguicolors I lost all my colorscheme, to solve I had to add the following lines:

" set Vim-specific sequences for RGB colors
let &t_8f = "\<Esc>[38;2;%lu;%lu;%lum"
let &t_8b = "\<Esc>[48;2;%lu;%lu;%lum"

I just released v2 of vim-hexokinase. It's scrapes asynchronously and has 6 different methods for displaying the colours in a file!

To upgrade, run git pull && make hexokinase. For more information on migrating to v2, check out :h hexokinase-v1-migration. There are a few fully deprecated options (:h hexokinase-v1-deprecation) but almost everything has a v2 alternative. v1 will still work and can be forced by using :let g:Hexokinase_v2 = 0.
