/u/breckenridgeback did a good technical response above on this.
Basically printers use a different set of primary colours, (CYMK).

You know of Red, Green, Blue.
But really there is also Hue, Saturation, Chroma.
That makes a crazy huge number of more colours from what is seemingly an infinite rainbow.

Reply to ELI5: Why do imaginary numbers even need to exist? by Tharsis101
This is my basic understanding. One small use for them....
Maths functions are to describe relationships between things.
You can graph these relationships.
If the relationship is exponential, you can incorporate squared items.
But if the result is always -ve, it can be better to write the function with an imaginary number in it.
Then you can also manipulate the function without losing the property of a -ve square.
