The colors are different inside and outside the tmux session

exdis commented 3 years ago

What Operating System(s) are you seeing this problem on?

macOS

WezTerm version

20210917-081523-9f5d0df1

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

Colors inside tmux session are quite different from the ones I specified in the settings. Outside of tmux session everything is ok. Outside:

Inside tmux:

To Reproduce

I just start a new tmux session

Configuration

local wezterm = require 'wezterm';

return {
    term = "screen-256color",
    enable_tab_bar = false,
    font = wezterm.font("FiraCode Nerd Font", {italic = false}),
    color_scheme = "Gruvbox",
    color_schemes = {
        ["Gruvbox"] = {
            foreground = "#ebdbb2",
            background = "#282828",
            cursor_bg = "#ebdbb2",
            cursor_border = "#ebdbb2",
            cursor_fg = "#282828",
            selection_bg = "#655b53",
            selection_fg = "#ebdbb2",

            ansi = {"#282828", "#cc231c", "#989719", "#d79920", "#448488", "#b16185", "#689d69", "#a89983"},
            brights = {"#928373", "#fb4833", "#b8ba25", "#fabc2e", "#83a597", "#d3859a", "#8ec07b", "#ebdbb2"},
        }
    }
}

Expected Behavior

Colors should be the same

You're setting term to screen-256color which is the wrong TERM configuration for wezterm; screen-256color is appropriate for applications talking directly to certain versions of GNU screen and older versions of tmux.

Leave it out of your wezterm configuration to use the default of xterm-256color!

I'd recommend that you also use the following in your tmux config so that clients inside tmux use the modern tmux terminfo, and so that tmux knows that it can use true color:

set -g default-terminal "tmux-256color"
set-option -ga terminal-overrides ',xterm-256color:Tc'

Thank you very much for the explanation! Now it's all displayed correctly.

Thanks a lot for this @wez. I had been banging my head on this issue which is also present in Alacritty and I couldn't find the answer anywhere. Your tmux config works like a charm (second line) and now colors in Tmux are displaying properly finally!
