dark theme doesn't match repo and is hard to read

[hoshsadiq]

Hello, I'm unable to replicate the dark theme on the README here. This is the diff for git diff 13e39b1~10. This is not necessarily an issue with delta, and could very well be my terminal setup in general. How can I go about debugging what the reason is for this? The annoying thing is this is a similar output even when I use a different theme.

This seems to be an issue with tmux and alacritty, in that, 24 bit colours aren't properly set up. Adding below to my .tmux.conf fixed the issue.

set -g default-terminal "tmux-256color"
set -ga terminal-overrides ",xterm-256color:Tc"

Great, sorry I didn't reply to this before you fixed it! Let me know if the README can be improved.

Note that the COLORTERM env var needs to be set correctly too. This is especially important when using delta over ssh, since ssh usually discards COLORTERM.

export COLORTERM=truecolor
