|Next I create a layer underneath the line layer and slap on some basic tones of color. I try to get sort of a middle value of each different material. Be loose and sketchy here.|
|Next start to add some shading (e.g. here visible in the lighter tones of the cowl). I also start detailing and cleanup. Here I used the pen tool to get clear and sharp edges for the warhammer and shoulder armor.|
|Go from space to space and continue refining and cleanup. I first finished all metal parts before going to other areas.|
|Once all areas are cleaned up and correctly shaded, go over the whole image and start the detailing phase. Original image: keirea.deviantart.com|
The advantages of this workflow are speed and an included color sketch. The downside: you have to choose your color scheme very early on.
TIPP: You can always easily check values on your color paintings by just adding a layer ontop everything in PS, fill it with black and set blend mode to saturation. You can turn this layer on and off to check your greyscale values.
