I recently needed to move from VSCode to PhpStorm IDE, and I would like to know if there is a way to export my color theme too. Here is the theme I use in VSCode.
Because the theme is a JSON file, I'm pretty sure there is a way to do it, but I don't know how.
This can't be done; in PhpStorm, themes are not JSON files but java LAFs. However, we have plenty of themes available in the repository, see https://plugins.jetbrains.com/search?headline=164-theme&products=phpstorm&tags=Theme., please check Cyberpunk Theme or CyberpunkUI Color Scheme, for example.
If none of them looks good for you, you can try developing your own one. Here are the guidelines for creating a custom theme plugin/customizing a theme
