How to Color Skin with SAI
1
Start with the basic light skintone, dont worry about getting it on the other areas cause this is on a separate layer anyway Pick a darked tone (not to dark) than the color you used for base, depending on where you want the light to be, add some sha
2
Before moving on pick the airbrush tool, have the density on very low(density is how hard it will appear ) Having the same dark color go over the shadows area again, to make it smooth Pick an even darker color and apply over the shadow area again
4
Same again but not with the airbrush this time, but with the water tool, (pick a color before using the water-tool) make the light and shadow areas smooth the cheeks too and add some highlights
