About:
Gray is a macOS utility that enables users to apply light or dark appearance settings on a per-application basis. It provides a user-friendly interface to manage and switch between system-wide themes without requiring complex terminal commands. This tool is ideal for users who want to customize their visual experience for individual apps.
Key Features:
  • Per-app theme assignment
  • Automatic theme switching
  • Simple, intuitive user interface
  • Support for both light and dark modes
Use Cases:
  • Customizing specific apps to use light mode while the rest of the system uses dark mode
  • Creating a consistent visual experience for development tools that have poor dark mode support
Alternatives:
  • Appearance – Built-in macOS setting that only allows system-wide theme changes
  • NightOwl – Similar functionality but with different pricing and feature set
