This is red and black theme for btop. You can use it for your red and black rice or for other rices, because it is very easy to rewrite hex-codes of colors in this config.

This theme works correctly on

• MacOS 26 Tahoe
• MacOS Sonoma
• Gentoo openrc
• Arch Linux and arch based distributions

I didn't test this config on other distributions but I think that it will be work correctly

Installation (universal)

https://github.com/S0LYER/red-btop
mkdir -p ~/.config/btop/themes
cd ~/red-btop
cp red.theme ~/.config/btop/themes

Applying this theme

nano ~/.config/btop/btop.conf

Then you need to find line "color_theme" and rewrite it:

color_theme = "/home/NAME_OF_YOUR_USER/.config/btop/themes/red.theme"
