// Actually verifying that the expected colors are printed is exceptionally
// difficult as:
// a) The color emission varies by OS.
// b) The logic checks to see if the printer is writing to a terminal, making
// mocking hard.
// c) Actually probing what gets written to a FILE* is notoriously tricky.
//
// The least we can do is to exersice the code - which is what we do here.
// The test will print each of the colors, and can be examined with human
// eyeballs.
// This can be enabled or disabled with ENABLE_PRINTER_TESTS
