TMUX and Fish (colors arent correct)

[SpiralUniverse]

So basically i want to open foot load tmux and fish but eveything colors is incorrect (inside tmux vs outside tmux) ive tried to fix it manually but i couldnt
i narrowed it down the problem lies within

    # Custom sequences (if file exists)
    if test -f ~/.local/state/caelestia/sequences.txt
        cat ~/.local/state/caelestia/sequences.txt
    end

i need help to identify what is the problem that makes tmux read this file incorrectly PLS HELP

Your colors are correct outside tmux but not inside ? Have you looked into this: https://github.com/tmux/tmux/wiki/FAQ#how-do-i-use-a-256-colour-terminal ?

OKAY I FOUND A SOLUTION
starting from the link your shared yes I did set everything as it was saying but it wasnt working
it turns out the problem is very simple to solve!
those sequences were being coded twice!
when running foot terminal
and when running fish inside tmux (which was giving the wrong colors)

Just replace those lines mentioned (sequence and if statement) with the following:

# Custom sequences (if file exists)
# Only apply if NOT inside tmux
if test -z "$TMUX"; and test -f ~/.local/state/caelestia/sequences.txt
    cat ~/.local/state/caelestia/sequences.txt
end
