Changing the font color dynamically in react has many benefits. Some of them are:

  • Drawing the user's attention by emphasizing key language or calls to action.
  • Giving text information visual emphasis or hierarchy.
  • Changing the color of text based on user preferences or system settings.
  • Constructing a color-coded system to classify or organize text.
  • By dynamically changing the font color, you may add context and visual appeal to your text content and make the user experience more interactive and interesting.


In React, you may use state or props to save the color value and then apply it using inline or CSS styles to alter the text color dynamically. A child component may also receive a color value as a parameter and use it to design the component. We can also use libraries like:

  • Emotion: This library contains features like source maps, labels, and testing tools. It offers fantastic developer experience in addition to strong and predictable style composition. JavaScript CSS styles may be written with the library Emotion.
  • styled-components: This library is used to create a styled component that can accept a color value as a prop and use it to style the text.


For more information about changing the color of the text dynamically in React, refer to the code given below.

let timeOfDayColor = 'blue';
let timeOfDayMessage = 'Good Evening';

if (curretnTime < 12 && curretnTime >= 0) {
   timeOfDay = 'morning';

   timeOfDayColor = 'green';
   timeOfDayMessage = 'Good Morning';

} else if (curretnTime >= 12 && curretnTime <= 18) {
   timeOfDay = 'afternoon';

   timeOfDayColor = 'purple';
   timeOfDayMessage = 'Good Afternoon';
}

ReactDOM.render(
