There are only five paints (6 if you include the nedium) in use here. All the variations in tone and colour were done by either wet blending the paints - much easier with these thick, heavily pigmented paints - or layering them one over the other. The skin and hair were done using Nighthaunt Gloom (which is basically a grey blue contrast paint and is one of the most useful shades I have).
Some moss effect was added on the bases to finish them off.
The biggest advantage of these paints is, of course, speed. These four figures took about an hour and a half from start to finish including drying time.
Next up: more Nappies and some 3d printed scenery.
