Create and use our own custom colors

[python128]

We should be able to make our own colors, and use them wherever we want.
Example:

use colored::*;

fn main() {
let greyish = make_color!(100, 100, 100); //In this, 'make_color!' macro is the syntax to make a new color, which we can use anywhere by:
println!("{}", "Hello".greyish()); // So that we don't have to keep typing 'truecolor(....)' and so on...
}

Felt it would be nice..
