There are 4 colors in the Gaianotes “flesh” line. I treat 051 & 052 (Flesh and Flesh White) as the “base” and add a bit of 053 & 054 (Flesh Pink and Flesh Orange) to tint the skin cool or warm. Then add even more of the chosen tint color to airbrush the shadows.
051 Flesh + 054 Flesh Orange
Example:
052 Flesh White + 054 Flesh Orange
Example:
052 Flesh White + 053 Flesh Pink
