How to generate random RGB color?
Introduction
Colour coding in digital systems can be implemented using various models, with RGB being one of the most widely used. The RGB model defines colours through a combination of three primary components: Red, Green, and Blue. Each component represents an intensity value ranging from 0 to 255, allowing for a total of over 16 million possible colour combinations.
The values for Red, Green, and Blue are combined to produce the final colour. For example, pure red is represented as (255, 0, 0), green as (0, 255, 0), and blue as (0, 0, 255). Intermediate colours are created by varying the intensity of each component. This model is foundational in digital displays, web design, image processing, and software interfaces.
For better readability and consistency across platforms, RGB values are often expressed in hexadecimal notation. In this format, each 8-bit colour value is converted to a two-digit hexadecimal number and combined into a single six-character string, prefixed with a hash symbol (#). For instance, #FF0000 represents red, #00FF00 green, and #0000FF blue.
This hexadecimal representation is widely supported in HTML, CSS, and graphical design tools, offering a compact and standardized way to define colours in digital environments.
