Guzmania species ID?

[meka]

Considering there are so many species of Guzmania, I'm not sure if you'll be able to identify this one, but I'll give it a shot anyway. Any ideas on the species of this one?

'passion'

I keep going back and forth between that and 'Luna.' In this picture that I found, it's much closer to the color of the one on the left ('Luna') than the one on the right ('Passion'). Is 'Luna' common enough that this would be possible?
