## What it is
Gray is a macOS application that lets users set light or dark appearance on a per-app basis under the system-wide dark mode introduced in Mojave. It works by writing the NSRequiresAquaSystemAppearance preference for selected apps and restarting them.

## Use cases
- run light and dark apps side by side on macOS
- force a specific app to stay in light mode while the system uses dark mode
- toggle dark appearance per application without terminal commands
- customize which macOS apps use Aqua appearance

## When to choose
- you want a simple GUI to mix light and dark app appearances on macOS Mojave or later
- you prefer not to run defaults write commands manually

## When to avoid
- you need per-app theming on macOS versions where the preference no longer works
- you cannot tolerate apps restarting when appearance changes
- you need an actively developed tool with recent updates
