1. Using the names of colors
Basic color names
The most general way to describe a color is by its name. Colors like red
and yellow that possess color are called chromatic and those that do
not, such as white, gray, and black, are called achromatic. The names
of the twelve basic colors are red, red-orange, orange, yellow-orange,
yellow, yellow-green, green, blue-green, blue, blue-violet, violet, and
red-violet. The names of the three basic achromatic colors are white,(3) Saturation
Saturation is a measurement of how much hue there is in a given color, or
gray, and black.
how vivid the color is. Colors that are composed of one main color are seen

Colors also sometimes earn names after many years of usage. This

Relative colors
This category is for basic colors that have had an adjective added to its
name, such as light blue, dark brown, or deep purple.
2. Using the three main characteristics of colors
Though there are many color models, the one introduced here uses the
three characteristics, hue, brightness, and saturation. Though using
color names is convenient, it can be found to be inaccurate. By using
these three characteristics of colors, you can describe a color very
accurately.
(1) Hue
Hue describes the fundamental color in a given color. The hue is
determined by the wavelength and energy pattern of the light.
