Thanks everyone who chimed into my first help request.
I picked up a set of winsor newton acrylic paint and a paint pen. That was definitely the right advice.
The red could go straight onto the board, but all the other colors needed to be backed by white.
Does anyone have good tips on mixing skin colors for paints? Right now all of these on the board were solid colors ,
start with an "earth color"; Something like yellow ochre, transparent oxide yellow, raw umber, burnt umber, raw sienna, transparent oxide red, or transparent oxide brown , it depends on the color of the skin.
Then mix that base color with white.
You can cool down or add "blush" your skin color by mixing it with hints of blue or red.
As an aside ; It's helpful to map out your paintubes in a saturation/hue color wheel based on pigments It will help you get an idea of how your pigments compare in temperature and how to mix them.
Here is a similar color wheel arranged by saturation and ligthness
