Huh, that is quite odd. Have you set tmux to true colour? If not that may be the issue, though I don't see why it would select those specific colours.

Incase you haven't, here's the configuration to do so. Place the following in your tmux.conf located at ~/.config/tmux/tmux.conf or ~/tmux.conf

set -g default-terminal "screen-256color"

you should have to run tmux source ~/.config/tmux/tmux.conf to get it to reload

You may also have to add the following to your nvim config:
set termguicolors

or set TERM to xterm-256color in your shell (example: export TERM="xterm-256color" for bash)

Though I doubt either are your problem.

Edit: fixed neovim configuration
- Thanks for helping. But No luck with those. Tried them all. vim said there's no option like "term". Other two doesnt work :(
  
  vim or neovim? what terminal emulator are you using? post your nvim init.lua file. try putting both of these in tmux.conf:
  
  set -g default-terminal "xterm-256color"
  
  set-option -ga terminal-overrides ",xterm-256color:Tc"
  
  This is for alacritty terminal emulator + tmux + neovim but may help put you on the right track with whatever te u might be using:
  
  Ah shit, that sucks, sorry to hear.
  
  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?
  
  Foot. It says foot. When I'm in tmux it says tmux-256color
  
  Try this in tmux.conf:
  
  set-option -ga terminal-overrides ",foot:Tc"
  
  These overrides apply to the TERM you are using outside of tmux (where this is running).
  
  man! its fixed. thanks!!
  
  Im really sorry that I couldn't reply soon. I'll try it out
  
  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
  
  This must be incredibly frustrating
