I use the color layer on the bottom, in normal mode, and put the greyscale layer on top, using the overlay mode on it.
As a rule, the result is not ideal the first time, and after that I simply adjust the brightness, hue and saturation of the layers, achieving the desired effect by touch.

Thank you! May I ask how you add the colors to the greyscale image?
