It's not clear yet what Rayleigh has actually taught Luffy (currently at chapter 600)
However after staying on that Island for 2 years, with Rayleigh being able to use all 3 types of Haki, it's pretty obvious that he's going to teach Luffy the same. Plus in chapter 599, Luffy used the colour of the conquerer to subdue the fake Luffy, which was already established as his type preference.
3 types of Haki to learn:
Kenbunshoku Haki - Color of Observation
Busoshoku Haki - Color of Armaments
Haoshoku Haki - Color of the Conquering King
