What is the HEX code for macOS System Mint in light and dark mode?

In light appearance, System Mint resolves to #00C8B3. In dark appearance, it automatically adapts to #00DAC3.

How do I bridge NSColor.systemMint into SwiftUI?

In SwiftUI views on macOS, instantiate Color(nsColor: .systemMint) to access the native AppKit dynamic color token.

Does System Mint adapt to Dark Mode and vibrancy in macOS?

Yes, NSColor.systemMint is an appearance-aware NSColor that updates automatically when switching between light and dark modes or across vibrant desktop materials.

Why use AppKit system colors instead of hardcoded hex values?

NSColor system tokens adapt automatically to user accent color preferences, Dark Mode, and accessibility contrast settings.
