Really? I could have sworn they said Gameboy Color on them. Maybe I'm crazy. Maybe they were backwards-compatible. I seem to recall that they had real color, too.
I wish I had them on-hand to check.
They're "black cart" titles. Dual-mode. As I said, Yellow is too, really. And all of those (as well as the original game) have nice Super Game Boy features. They removed the SGB logos from the backs of the US boxes for all compatible titles, but it IS still there.
Dual-mode GB/GBC games have both GB and GBC versions of the game on the cart. Usually it's the same thing just on one system there's no color, but in a few cases the game is actually different on each system, though that is rare. The only game that is actually different on each system that I know of is Conker's Pocket Tales; all others are just colorized versions of the B&W game. A few games do make save files incompatible between the two systems, though, like Wario Land 2... that was kind of annoying, because it only has one save slot and there are no differences I could see in the actual game, so why was the save file locked to GB only or GBC only? But anyway, the Pokemon games are the more common kind of colorized game whose save files are compatible between systems. The games are the exact same thing either way as far as I know, it's just that one way there is more color. ("more" because the SGB uses the B&W modes of course, it just changes the colors, adds a background, etc.) Actually a black cart title.
(Are there any actual gameplay differences between B&W and color?)
If you look at the Pokemon Gold/Silver box, it doesn't say "Game Boy Color Only" on it, and on the back there are both GB and GBC logos and there is one screenshot of the B&W version. Crystal, on the other hand, does say "Game Boy Color only", and only has the GBC logo, and only has color screenshots. Actually a clear cart title.
For most GB games it's easy to tell the difference -- B&W games are grey (with, apart from Pokemon an SGB logo on the cart if it has SGB enhancements, though a game or two incorrectly has such a logo...), dual-mode black (with an SGB logo on the back of the box if it has SGB enhancements, apart from the Pokemon games where Nintendo removed the logos in the US), and color-only games transparent. With Pokemon it's a little tougher because of the special cart colors.
