RGB to Hex and Hex to RGB

When working with colors in web development, it is common to come across RGB and hex color codes. RGB stands for Red, Green, and Blue, and it represents a color by specifying the intensity of these three primary colors. On the other hand, hex color codes are a shorthand way of representing colors using a combination of six hexadecimal digits.

In this blog post, we will explore how to convert RGB to hex and hex to RGB using JavaScript.

Converting RGB to Hex

To convert an RGB color to a hex color code, we need to convert the decimal values of each color component to their hexadecimal equivalents. Here’s a function that accomplishes this:

function rgbToHex(red, green, blue) {
  const r = red.toString(16).padStart(2, '0');
  const g = green.toString(16).padStart(2, '0');
  const b = blue.toString(16).padStart(2, '0');
  
  return `#${r}${g}${b}`;
}

Here’s an example usage of the function:

const hexColor = rgbToHex(255, 0, 0);
console.log(hexColor); // Output: #ff0000

Converting Hex to RGB

To convert a hex color code to an RGB color, we need to extract the individual color components from the hex code and convert them from hexadecimal to decimal. Here’s a function that accomplishes this:

function hexToRgb(hex) {
  const r = parseInt(hex.substring(1, 3), 16);
  const g = parseInt(hex.substring(3, 5), 16);
  const b = parseInt(hex.substring(5, 7), 16);
  
  return `rgb(${r}, ${g}, ${b})`;
}

Here’s an example usage of the function:

const rgbColor = hexToRgb('#ff0000');
console.log(rgbColor); // Output: rgb(255, 0, 0)

Now you have the tools to convert RGB to hex and hex to RGB using JavaScript. These functions can be handy when working with colors in your web development projects.

Remember to always validate user input and handle edge cases to ensure the functions work as expected.

Happy coding!
