The Game Boy Color (ゲームボーイカラー Gēmu Bōi Karā"?) is Nintendo's successor to the Game Boy handheld game console
The resultant product was backward compatible, a first for a handheld system, and leveraged the large library of games and great installed base of the predecessor system.

Wikipedia doesn't split the numbers for Game Boy and Game Boy Color though. Frankly, I always considered it with the Game Boy. However, it did release about 9 years after the original and wikipedia has Game Boy 4th generation and Game Boy Color 5th.
