Gray for Mac

Personalize app themes on macOS

Gray is a free macOS utility that lets you assign light or dark display modes to individual applications. Instead of toggling the entire system appearance, you can pick a separate look for each app so your workspace matches your needs and tastes.

How it operates

The tool runs quietly in the background and applies the chosen appearance whenever an app is active. This makes switching between apps with different visual styles effortless and keeps system-wide settings untouched.

Main advantages

• Preserves a consistent visual feel across different programs without changing the global appearance.
• Offers per-application theme controls through a compact, easy-to-navigate interface.
• Lightweight and available at no cost, making it a low-effort addition to your setup.
• Especially convenient for people who alternate between light and dark modes often.
