In the case you mentioned, they would definitely go outside of the quotes. Here's an example: '''Craig told Clyde that his jacket was not "navy blue", it was just "regular blue".  He said, "It's just the way I like it." "I agree," responded Clyde, " it is an 'awesome blue'."'''

So it all depends on the context. If you're just quoting words, punctuation goes on the outside. If you're quoting a whole phrase, it goes on the inside. I felt like I may have been confusing by answering more, so here's a "tl;dr": In that case, the comma goes on the outside of the quotes.
