Currently, Moe doesn't display correct colors when using 24 bit color on Konsole. So, you need to use 256 color mode on Konsole.
You need to set colorMode
in your configuration file like this.
$ cat ~/.config/moerc.toml
[Standard]
colorMode = "256"
Please set $TERM
to xterm-256color
. Otherwise, it may not work properly. This is a Ncurses limitation.
