I really like this name, but I happen to like particularly weird-sounding or obscure names. I especially like color names. This one sounds kinda funny as a name but I do like it. It's dope.
Unlike other commenters, I think that this would make a fantastic first name. I'm not sure as to why someone by the name Porfirio would be subject to teasing.
I love it and it would be better as a middle name than a first name. Other than that, it makes me think of Porfirio Diaz and of little holes in rocks from when there are gas bubbles in them when they're forming (porphyry).
I adore Porfirio, but I could never use this on a human child, the poor kid would never hear the end of it. (Maybe as a middle?) He sounds so lovely and has such an artistic vibe! But never as a first name. :(
