Sorry for the late reply, got busy in the last few weeks. I haven't tested it yet with tmux, but my guess is because orange isn't the part of ansi color name (red,yellow,green,blue,cyan,magenta,white) and thus tmux couldn't know it

Now I'm not sure about this. Can you provide the whole tmux.conf and .bashrc (or whatever the file you use to define TERM=screen)

[RossComputerGuy]

My .zshrc does not define TERM and I do not have a tmux.conf file.

Hi, may be do you have forget "set termguicolors"
Try witch Kitty? i have a color on Kitty but not on Tmux or Alacritty :(

[RossComputerGuy]

Ok i have the same error with Alacritty + Zsh and without set termguicolors...
TERM=xterm ?

I faced same issue with MacOS + Alacritty + tmux.
I added this line to my .tmux.conf then worked.

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