I wanted to create a Mailspring theme which better integrates with dark theme on Pop!_OS. So my colour choices were deeply inspired by this operating system. Since this is a dark theme, it is necessary to modify the style of email messages to be displayed correctly. For this reason I reused the code from a Predawn Mailspring theme. So all the credits go to asparc.
- Download Mailspring
- Download the latest version of the Pop!_OS theme
- Unzip
- In the Mailspring, click Edit > install theme and select the unzipped folder
- Enjoy :)
