If you are an artist, photographer, graphic designer, or web developer, having a firm understanding of colors is a necessity. Key to being able to study and discuss colors is a formal framework for quantizing their properties. Abstract mathematical models called color models do just this, allowing people to discuss the qualities of a color in a consistent manner. These models usually assign tuples of numbers to a color, often either ordered triplets or quartets, where each value represents a property of the color. This post will introduce one the most popular models: the RGB color model.
