Interesting looks solid to me.
Some nit-picks:
* Coloring on Posix depends a ANSI terminal. Can you check that a
  terminal is ANSI compatible?
* There are some magic numbers in the code. These may be difficult to
  figure out for maintaining.
* enum Color should maybe be same on all systems.
  This is a rather small issue. But I may transfer the Color to another
  system. So if it is possible there should only be one enum Color for
  all systems.
* Call it terminal or similar. Because other terminal related stuff can
  be added and IMHO it's a better name.

I have written a similar library. Not finished. Let's join forces.

Johannes Pfau has written a progress bar. I will add this.
