I really like the i3 blocks status bar with a few colors.

But after installing (full) LaTeX, all icons/emojis are really colorful, now, which I don't like.

How can I go back to the beautiful monochrome icons without uninstalling LaTeX?

In my i3 config in the bar block, I have the following:

font pango:DejaVu Sans Mono for Powerline, FontAwesome 12

And I don't know why the colorful icons/emojis are used now?

Thanks a lot for your help.
