What's the minimal image resolution for retouching colors?

If i use editor such as Lightroom, what's the minimal resolution of image i can use to get meaningful results and what is the recommended resolution?

Corrections i am interested in is color corrections.

Asking because there are cameras with different number of megapixels available so i am not sure weather 12mp is enough or i need 16mp? 24mp or 36mp?
