PlatformColor

Important: The Vega SDK supports many of the React Native version 0.83 components and APIs. You can use the supported components and APIs in the same manner as an ordinary React Native app. This page lists a specific React Native feature supported by the Vega SDK and contains React Native V0.83 documentation from the reactnative.dev website created by Meta and other contributors and licensed under the Attribution 4.0 International License. For more information about React Native V0.83, see the React Native documentation, version 0.83. For the most current feature information, see the Release Notes.

Important: PlatformColor is not currently supported on Vega. The colors it references resolve only on Android and iOS; on Vega the value does not resolve to a native color.

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

Note: If you're familiar with design systems, another way of thinking about this is that PlatformColor lets you tap into the local design system's color tokens so your app can blend right in!

Example

Copied to clipboard.

import React from 'react';
import {Platform, PlatformColor, StyleSheet, Text} from 'react-native';
import {SafeAreaView, SafeAreaProvider} from 'react-native-safe-area-context';

const App = () => (
  <SafeAreaProvider>
    <SafeAreaView style={styles.container}>
      <Text style={styles.label}>I am a special label color!</Text>
    </SafeAreaView>
  </SafeAreaProvider>
);

const styles = StyleSheet.create({
  label: {
    padding: 16,
    fontWeight: '800',
    ...Platform.select({
      ios: {
        color: PlatformColor('label'),
        backgroundColor: PlatformColor('systemTealColor'),
      },
      android: {
        color: PlatformColor('?android:attr/textColor'),
        backgroundColor: PlatformColor('@android:color/holo_blue_bright'),
      },
      default: {color: 'black'},
    }),
  },
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
});

export default App;

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 in the preceding example.

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