PlatformColor

PlatformColor(color1, [color2, ...colorN]);

You can use the PlatformColor function to access native colors on the target platform by supplying the native color’s corresponding string value. You pass a string to the PlatformColor function and, provided it exists on that platform, it will return the corresponding native color, which you can apply in any part of your application.

If you pass more than one string value to the PlatformColor function, it will treat the first value as the default and the rest as fallback.

PlatformColor('bogusName', 'linkColor');

Since native colors can be sensitive to themes and/or high contrast, this platform specific logic also translates inside your components.

Supported colors

For a full list of the types of system colors supported, see:

• Android:
  • R.attr - ?attr prefix
  • R.color - @android:color prefix
• iOS (Objective-C and Swift notations):
  • UIColor Standard Colors
  • UIColor UI Element Colors

Example

The string value provided to the PlatformColor function must match the string as it exists on the native platform where the app is running. In order to avoid runtime errors, the function should be wrapped in a platform check, either through a Platform.OS === 'platform' or a Platform.select(), as shown on the example above.

Note: You can find a complete example that demonstrates proper, intended use of PlatformColor in PlatformColorExample.js.
