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

I'll say this. To be a succesor, for me. The system has to have higher than single digit original exclusive games. And most have to be close to million sellers. For me to count it as a new system. Because than, people are looking at it, as a new system. Rather than some upgrade, like the GB Pocket/light was.

Only I'm not looking at it from anyone's perspective other than what Nintendo's own information shows and that is GBC was and is an upgrade, good on them it performed like a successor still doesn't change what it was and that is a redesigned GB.
