Was the Game Boy Color a successor to the original Game Boy?

What about the DSi then? For those that say the exclusives make it a real successor, if you call the GameBoy Color a seperate generation so should you the DSi. Also, a sales number being available or not isn't relevant either, because we also know 3DSXL or even GameBoy micro sales numbers.

Nintendo says GameBoy Color is a variant of the GameBoy, and that's all we need to know. They have and are presenting it as one device as they do with DS/DSi and 3DS/n3DS.

DSI has 6 exclusive retail titles.

GBC has 416 exclusive retail titles.

GBC is a successor, it is a 5th generation console, the Gameboy is a 4th generation console released almost 10 years prior.
