Edit the theme of my subtitles
When you create your project, you choose a theme for your subtitles. If this theme doesn't suit you, you can always change it after you've created your project. Here's how.
Open the editor for the project in question. Then click on the gear icon in the top right-hand corner.
Then, in the right-hand menu, click on the theme name, "Neutral" in my project.
A menu opens, allowing you to select the most suitable theme. If you want something neutral, you can choose the Neutral theme.
Confirm your choices by clicking on "Apply this theme".
