Afterburn Theme

IDE Theme GB Studio 4.2.x
Afterburn Theme for GB Studio 4.2 — dark purple IDE theme

Dark IDE theme with subtle purple hues and pink highlights. Based on the default dark theme with desaturated purple tones across all panels, giving the editor a cohesive, easy-on-the-eyes look for long sessions.

Extract the AfterburnTheme folder to your GB Studio global plugins directory:
macOS: ~/Library/Application Support/GB Studio/plugins/
Windows: %APPDATA%/GB Studio/plugins/
Linux: ~/.config/GB Studio/plugins/
Then restart GB Studio and select Afterburn under View → Theme.
