I started using Fish (and oh-my-fish) a couple of weeks ago and one of the things that I find somewhat visually hard is the default background color of the autocomplete options (see the purple background in the image). I tried looking in the Fish page, but couldn't find anything related to that. I'd like to know how that background color can be changed. In case you're wondering, I'm using LXTerminal in LUbuntu (a Ubuntu distro with LXDE).
it's more convenient to setup all color configuration via fish web UI, which can be done from cli:
fish_config colors
, which launches the config server of fish, and there are already tons of predefined color suggestion
