How to set environment variables for the calibre program (to get dark theme) in Mint Cinnamon [solved]

I'd like to change the theme of Calibre and the developer has made his program quite customizable:
https://manual.calibre-ebook.com/customize.html#id1 . According to that link, we can use "CALIBRE_USE_SYSTEM_THEME".
My question is: How do we set this environment variable on Linux Mint Cinnamon?
Thanks!

In analogy, the variable CALIBRE_USE_SYSTEM_THEME could be set in the same way:
env CALIBRE_USE_SYSTEM_THEME=1 calibre
Really, the
online help could be a bit more specific on how to set the (optional) environment variables on Linux systems.

karichen,
initially, i tried env CALIBRE_USE_SYSTEM_THEME=1 calibre but it did nothing. i then tried env CALIBRE_USE_DARK_PALETTE=1 calibre and it worked. the developer said he didn't give instructions for linux because there's multiple answers (because there's multiple linux flavors)

FYI, they moved this into an option under Settings > Preferences > Look & Feel > Main Interface > Color Palette

Thanks, Jeff. I appreciate this helpful information. I've made the change in that place you instructed. Now there's no need to mess with the terminal.
