On this page there's two kinds of blue: the icy light blue and the dark blue. I've got a feeling the blue in this drop is the dark blue variation sadly.
It's possible that the white is in fact a very light blue although I think that's just wishful thinking on my part.
But yeah pictures of the backlight would be wonderful
