Sorry on that command if you're using lua to configure the correct setting should be
vim.opt.termguicolors = true
Or in your init.vim set termguicolors should work too. Apologies for messing up that last comment
If you're still up to trying some stuff, last thing I can think of is tmux deciding not to take the setting. Forcing tmux to use true color may help with set -ag terminal-overrides ",$TERM:Tc" or launching with tmux -2 may help, you'll have to source the tmux config again of course. Also confirming that your terminal supports true color
I tried that. Not working. Im really sorry, I shouldve mentioned this on the original post itself. I did some searches and tried these already. Im really sorry
Yeah thought you may have done so, still good to check. Hope the best for you but I can't think of anything else myself, unless you have a background set in tmux and a transparent background in neovim
For others who may help, what terminal are you using? What is is the output of echo $TERM?
Yeah that's the expected output. I'd see if alacritty or kitty works as expected to rule out foot being the issue, then manually setting term=xterm-256color in your foot.ini if it does work in either
