Hi Bihai, I have a 'Big Black' that I swap with my friend here, he got it from Michael Bromeliads years ago. As my friend kept it in rather shade area, so it looked 'Big Green' !! when I frist saw it.

Anyway, after I've given the plant half a day sunlight for two month, its color gradually turns dark and nearly brown now. I think it would be black when mature nearly soon, then I will take a pic to show you.

Here my 'Big Black', the plant originally came from Micael's Bromeliads.

And another pic, [just a 'Little Black',hoping to grow up to be 'Big Black' someday]

I refresh this thread as I found something that really "Black",
it's Dyckia 'Lad Cutak' that I got from Michael's Bromeliads.

The plant is on the left, the other red one on the right is Dyckia fragrans
which came from Tropiflora.

These dark leaves Dyckia make me being doubtful that
why they could tolerate strong direct sunlight without any damage,
as we known that dark color collect more heat.
