Here's a question somebody asked recently about skin tone
Question: "What colours do you use in watercolour for skin tones?"
For me, it is always BURNT SIENNA
(Winsor & Newton in my opinion have the best tone of this colour and
I use it regularly.
In the above example I have tried to show the varying tones that can be achieved with clear water added.
(please note that some artists find other manufacturers just as good,
but in my humble honest opinion the W & N one wins hands down)
