(A12.1){{br}}
Throughout our existence we learned that all existing colours in nature can be created from three (red, green, and blue) basic natural (or better, elementary) colours. This sets the ground to define seven basic colours (000=black, 001=blue, 010=green, 011=turquoise, 100=red, 110=yellow, and 111=white). However, depending on the amount/intensity of any of the three (rgb) colours, we can create different shades of these basic colours, some of which we named as different colours. For instance by changing the intensity of the two components that naturally give us either orange or yellow, we can make a colour we named "brown". Note, that we are not even mentioning colour names with exotic prefixes, postfixes and odd colour compositions such as light-olive-green, yellowish-brown, bluish-pink, etc.
