Roblox Studio Themes generates a Visual Studio Code theme from Roblox Studio’s script editor default or custom colors. For more information, read about the generator on GitHub.
Roblox Studio doesn’t allow importing or exporting script themes. VS Code has thousands of themes. It’s not very practical to add VS Code themes to Roblox Studio.
I was browsing and found this plugin to do what you asked. From what I know, it connects to the Visual Studio Marketplace and imports the theme there into Roblox Studio.
v1.0.0 was just pushed out and marks the first stable version of the extension that I’m happy with. Roblox Studio Themes for VS Code now has an extensive test suite to ensure that syntax highlighting is an exact match to Roblox Studio.
Thank you all for your support in reaching stability. The VS extension has been unmarked as a Preview extension. Below are the changelogs up to v1.0.0
