We can change the font color based on the background color in react by few different ways: 

  • We can use a library that offers practical functions, including color contrast and brightness, to choose the best font color based on the background color. 
  • We may manually determine the contrast ratio between the background color and the text’s color. If the contrast ratio is below a certain threshold, you can choose a different font color to improve the contrast and readability of the text. This can be done by using a library ‘contrast.js.’ 
  • contrast.js: This is a library that helps in measuring the contrast between two colors. The contrast ratio gauges how simple it is to see text against a specific background color. 
  • We can use CSS ‘color’ function. 
  • color: This function allows you to use operations like lightening, darkening, and mixing to provide a color value that is generated from one or more other colors.
