From the manufacturer:
StarBrite Lite Skintone is by far the best flesh base on the market! It's so easy to build with washes and works amazing as a highlight.
This color is perfect for portraits but it can be used for a number of applications where a light skin tone is needed.
It mixes very well with anything; Brite White, Florida Moss, Medium Skintone, Dark Skintone, Lite Orchid, and Yellow Ochre
Gauge Size
The gauge size is the circumference of the smaller bar in the middle.
