This file contains variables with colors that you can use to color your strings when printing them.
Example...
// This will make all the text you print onwards blue,
std::cout << blue;
// This will be blue, and all the text after it will be red.
std::cout << "example" << red;
// This will be red.
std::cout << "Greetings, Universe!";
All the variables are ANSI escape color codes.
