One thing that seems to be confusing you is that in the examples given, a capitol letter indicates the mutant gene, while a small letter indicates a normal gene. Therefore, Pp is a pastel (one mutant gene), pp is a normal, and PP would be a super pastel (although there is no possibility of getting that in your original question).

I could go through and solve the question using my method, but that would probably only further confuse you.
Everywhere I have read the mutant (recessive) gene is lower case. Because Normal (dominant) is upper case... but as long as you know what you are reading it shouldnt matter I guess.
