Tillandsia and its pink blush

Lately I've been noticing how our Tillandsia, rescued from atop a garbage can, is slowly developing a pink/magenta blush along the areas where leaves meet.


Tillandsia - perched between wooden boards.

I'm hoping this is just an indication that it is recovering from its ordeal. I was also hoping that it would give me a clue as to what precise Tillandsia it is, but so far I'm still unable to identify it.
