The greyscale-to-color process can be very valuable, especially since greyscale can take less time and is thus more viable for showing to clients at early stages. A common error, though, is to assume that because your value structure is good, that those values are locked in. When converting to color, the human eye sometimes perceives vibrance and saturation as brightness or light value. Be aware of this and don't be afraid to correct your values again when adding color. I do think it's a good idea to figure out exactly how you're seeing values and to practice converting color to greyscale or vis/versa.
