ELI5: Explain Like I'm 5

Color model

Imagine you have some crayons - red, blue, green, and yellow. Now, let's say you want to make more colors. How can you do that? The answer is by mixing these basic colors together.

A color model is kind of like a recipe for mixing colors to get new colors. There are three main color models - RGB, CMYK, and HSL.

RGB stands for red, green, and blue. In this model, we use these three colors to create every other color. It's kind of like a video game, where each pixel is made up of these three colors.

CMYK stands for cyan, magenta, yellow, and key (black). This color model is often used in printing. To make other colors, ink of these four colors is laid down in layers before drying to form the final image.

HSL stands for hue, saturation, and lightness. In this model, we think about colors in terms of their brightness (lightness), how much color there is (saturation), and what the actual color is (hue).

So there you have it. A color model is like a set of instructions on how to mix and create colors using different pigments like light, ink, or paints.
