If you use Linux Mint, you likely prefer it over other Linux distributions. You may not like the default colour scheme though. While there are a few included alternatives, you may not like any of those either. Thankfully, Linux Mint has the built-in option to download third-party themes from the “Cinnamon-spices” website here.
To be able to download a new theme, press the Super key, then type “Themes” and hit enter.
Tip: The “Super” key is the name that many Linux distributions use to refer to the Windows key or the Apple “Command” key, while avoiding any risk of trademark issues.
Once you’re in the themes window, switch to the “Add/Remove” tab to view the list of available third-party themes. If you see a banner at the top advising you that “Your cache is out of date”, then you should click “Yes” or the “Refresh” icon in the bottom-right to update the list to the latest version.
Next, scroll through the list to find a theme that you think you might be interested in. To learn more about a theme and see a better preview image, select the theme then click the “More info” light-bulb button in the bottom-left corner. This will open the webpage for the theme in your default browser. To download a theme you like, click the relevant “Install” button on the right.
Once you’ve downloaded the theme, switch back to the “Themes” tab. If you click into any of the theme sections, you can then search through the list of options which will include the new theme settings you downloaded. To enable the new theme, just click on it and Mint will instantly apply it.
Tip: Not every theme comes with theme settings for every section, so if you can’t find the new theme option, try switching through the other sections too.
