Hexadecimal color (hex color) is a representation of colors using a six-digit combination of numbers and letters. It defines red, green, and blue (RGB) values in base-16. Each pair of digits represents the intensity of each color component, ranging from 00 to FF. For example, #RRGGBB, where RR represents red, GG green, and BB blue. This format is widely used in web design, CSS, and graphics, providing a convenient way to specify precise colors with millions of possible shades.

Hex colors are a universal and efficient way to specify precise colors in the digital world, making them crucial for designers, developers, and content creators to create visually appealing and consistent experiences.

RGB stands for Red, Green, Blue. It's a color model where colors are created by mixing varying intensities of red, green, and blue light. Each color component ranges from 0 to 255, allowing millions of colors. Combining these values creates a full spectrum of colors for digital displays and images.

RGB is used for digital color representation in various applications. It's vital in digital displays, photography, graphic design, and web development. By combining red, green, and blue, it enables precise color control, creating vibrant images, videos, and graphics for digital media and screens.
