Issue Description

I've set my .Xressources to use onedark first with urxvt. The colors palette is good in the terminal so I assume the Xressources is configured correctly.

I've managed to have one dark working let g:onedark_termcolors=256 but as you say in the README.md colors are darker than they should be.

With g:onedark_termcolors=16 I've got something like this:

My term look like this with Xressources:

Sorry if I've missed linked issue but I'm not sure what to look for and my research did not helped me.

Thanks in advance.

This was almost certainly caused by #201.

Does urxvt support an independent background color, for example as appears in https://github.com/joshdick/onedark.vim/blob/master/term/One%20Dark.Xresources#L3?

[sganon]

Yes there I've set it to the same as the theme:
URxvt.background: [100]#282C34

How should I tweak the backgorund property then ?

[sganon]

I've reverted to 6a98de0
(commit juste before PR #201) and the bug still exists, so maybe not this PR.

[joshdick]

Can you paste both your .vimrc and your .Xresources?

... Ther is more conf but not related to colors

For my vim config, is quite splitted so here is my repos with my conf:
https://github.com/sganon/my-dot-files/tree/master/vim

[sganon]

Well it seems only urxvt related but I haven't found any clue.
I will switch to a more modern terminal ^^.

Closing the issue, thanks for your help. :)

[joshdick]

No worries!

I wasn't able to reproduce locally with your ~/.Xresources, so one of these may have been the issue during your experiments:

• If you had tried enabling set termguicolors, it may have caused issues with urxvt since it doesn't seem like urxvt has true 24-bit color support: https://gist.github.com/XVilka/8346728#terminals-that-parse-ansi-color-sequences-but-approximate-them-to-256-palette
• Your urxvt config should have let you use g:onedark_termcolors=16 in your Vim config, but your current config has g:onedark_termcolors=256, which also may have caused the behavior you saw

You should have better luck using set termguicolors inside a more modern terminal, like you mentioned! 🙂

I'm having the same issue described here.
I am using xterm in Ubuntu 18.04.

I included the onedark palette in my .Xresources file:

And thisis how I setup my .vimrc

The terminal looks fine:

Here is the output of vim --version

Any idea what might be going wrong?
