RGB Value

In HTML, a color can be specified as an RGB value, using this formula: rgb(red, green, blue).
Each parameter (red, green, and blue) defines the intensity of the color between 0 and 255.
To display the color black, all color parameters must be set to 0, like this: rgb(0, 0, 0).
To display the color white, all color parameters must be set to 255, like this: rgb(255, 255, 255).
For example, rgb(255, 0, 0) is displayed as red, because red is set to its highest value (255) and the others are set to 0.
