Hi,

I'm new to both using Helix and terminal multiplexers in general, so I'd appreciate some help with this. When I launch Helix without tmux, I see the default theme with a purple background, which I like:

But when I launch it using tmux, even with the -2 flag, Helix does not display the same color scheme:

I have tried making a config.toml file with an [editor] section and set true-color to true, but that didn't appear to help. How can I use the default theme with tmux? I'm using GNOME 47 with wayland on Fedora, in case that matters.

Any post I've seen involving Helix, tmux & colors seem to be with custom themes, so I don't know which threads are relevant to this, if any.___

It's not a Helix problem, If I recall correctly it's about "true color (24 bits)" in tmux, you should try this on your tmux config https://gist.github.com/andersevenrud/015e61af2fd264371032763d4ed965b6#tmux

Sorry, currently I use Zellij, but I encountered this problem with tmux + neovim
