Beret Stormtroopers conversions.
I use non-GW colours, but it's not difficult to understand the corresponding GW ones. Colours diluted!
Here the tutorial.
Then a layer with a brown that tends to red (can I define it bestial brown?)
The same brown blended with "dwarf flesh" to paint another layer, avoiding deepest recesses (between fingers, mouth...).
Now the highlights. I repeat: diluted colurs!!
First "dwarf flesh" and then "dwarf flesh" blended with "elf flesh".
So the skin tone I use is very easy: a sequence of highlights with diluted colours. If we do a mistake we can correct it with the previous diluted colour.
