It does look like all the new models have black boot screens, while the older ones, probably up to (and including) 2011 models (Intel HD3000) have the white boot screen.
2013 15 retina.
If i boot from the internal drive, black.
If i boot from external, grey.
Well I corrected myself somewhere not long ago. The 2012 models still have grey/white boot screen, so black goes only for "current" laptops, 2013+, although that retina above me seems to be some kind of exception.Oddly, I think you're onto something. It's black on my 2013 nMac Pro6,1, white on our oldest mac (a 2011 27" iMac), and black on our new Mac Mini.
No other correlations come to mind.

Hey, I'm just wondering which boot screen you have? There's a black and white bootscreen. I think it depends on the models. The newest Macbook's got a black boot screen and the older ones got a white boot screen. And if so is it possile to change it?
Some stupid little question, but i'm just curious.
