Which of the following colours are called ‘primary colours’?

Primary colours are considered to be the basic colours that cannot be created by mixing another colour and are considered to be the foundation upon which all other colours have been created. Now, in the realm of colours and light, the primary colours created are known as RGB—red, green, and blue. The combination of these colours results in all the shades of light that have been created. On the other hand, when talking about physical colours, the primary colours created, abbreviated as “CMY,” comprise cyan, magenta, and yellow. The main contrast between these two colours lies in the following: in physical colours, “primary colours” is associated with light, whereas “primary pigments” is associated with mixing. In other words, the mixing of red and blue light creates magenta, whereas the mixing of red and blue pigments results in the production of purple.
