How to change the background color of a View dynamically in React Native

How to change the background color of a View dynamically in React Native:

This post will show you how to change the background color of a View dynamically in React Native. We will create one small application that will have only one screen with one View with a background color. If we click on it, it will change the color to some random color. You can keep clicking on it and it will again change to a different color.

Dynamically change the view color:

We can use the backgroundColor property to add a background color to a View. If the value of the property is assigned with a state variable, updating the state variable will update the background color of the View.

Let me show you how it can be done with an example:

import { useState } from 'react';
import {
} from 'react-native';

const randomRGB = () => Math.floor(Math.random() * 256);

const getRandomColor = () =>
  'rgb(' + randomRGB() + ',' + randomRGB() + ',' + randomRGB() + ')';

export default function App() {
  const [currentColor, setCurrentColor] = useState(getRandomColor());

  return (
    <SafeAreaView style={styles.container}>
        onPress={() => setCurrentColor(getRandomColor())}>
        <View style={[styles.view, { backgroundColor: currentColor }]} />

const styles = StyleSheet.create({
  container: {
    flex: 1,
    marginTop: StatusBar.currentHeight || 0,
    alignItems: 'center',
  view: {
    width: 100,
    height: 100,

  • The getRandomColor() method is returning a random color. The randomRGB() method returns one random value between 0 and 255. The getRandomColor() method uses the random values to create a color string like rgb(103,72,17).
  • The currentColor variable is initialized using the getRandomColor() method. It is a state variable and it can be updated with the setCurrentColor() method. Updating this value will rerender the component.
  • The background color property, backgroundColor is assigned as currentColor. So, it will show a random color to the View.
  • On pressing the TouchableWithoutFeedback component, it assigns a new value to the currentColor variable by using the setCurrentColor method. As this is a state variable, it will rerender the View component with the new color.

If you run this app, it will show a View at the center of the screen. If you tap on it, it will change the color randomly.
