Why is my tongue purple?

Last week I veered off of Walling Road and onto the fundraising/event planning path. It was quite a bumpy path and one that I hope I will not be heading down any time soon. Nonetheless, I was able to raise money for NYC kids and it appeared that all who attended had a good time. But in the weeks leading up to the event (Pong at Porky's: Play for Public Schools), I did a whole lot of stressing and not a lot of wine writing. So, this little anecdotes comes from a few days ago...
My parents were in town toward the end of September and purchased two bottles of wine for me - both at a reasonable cost and both red. Though they were from different continents and hemispheres, they were told that the two could be compared in a taste off (at least for value and flavor). Upon receiving these two gifts, I had every intention of cooking up a delicious meat sauce and hosting a small dinner party with one or two other couples. Of course, the days went by and things got more and more hectic as the day of the big event approached. I decided that instead of opening the two bottles simultaneously, I would just have to experience them on their own.
The 2006 El Seque Vinedos De Seque was opened. I was especially excited about this wine because I spent a semester in Alicante,,where it was produced, during my junior year. I poured a very judicious amount into my glass - there was just too much to do and I needed to be able to read for class, write and take notes, start research email guests and plan out the details of my party. I took a sip, swishing the wine as the wine pros do - all around my tongue to the back of my throat, in front of my teeth, coating my palate. I swallowed and tried again. This was certainly a big wine. After a few more sips my glass was gone and I went about my tackling my to do list.
About 15 minutes later I caught a glimpse of myself in the mirror. I looked strange; something was wrong. I stared and realized that my lips had a strange hue to them. I smiled and my teeth had a slight blue cast. I opened my mouth and stuck out my tongue... purple! My tongue was dyed a deep indigo. I had a sudden flashback to the days of devouring candy with names like "blue razzberry."

Now I know that it is quite common for people to get the red wine teeth (when your teeth lose their pearly white sheen and become a little gray). This was not the same thing. This was on a whole other level.... and I had only had a few sips! I was so preoccupied with the color of my tongue that I forgot the think about the flavors of the wine. I decided to wait until the next day to do another test. And of course the same thing happened. I have to wonder, what is it about this wine that made my tongue, my teeth and my lips take on a purple hue?

Tasting notes:
Strong, full bodied, well structured wine that was better on the 2nd day after opening. Slightly leathery, with good black/purple berry flavors. This wine is made from a blend of Monastrell, Cabernet Sauvingon, Syrah and Tempranillo. Did you know that Monastrell is more commonly known as Mouvedre? This wine would NOT be good for the following events: first dates, weddings, gallery openings, schmoozing parties, business dinners. It would however be fine to have on a night in, with a steak, a burger or lamb. $11.99
