@TurtlerChan those areas are made of "thinner" skin and what you're seeing is blood under those part of the skin

-shade is some shade of purple + your base color mixed
-highlights is some tint of yellow + your base color mixed

@TurtlerChan for example: skin isn't just one color and a whatever pink for blush and black for shadows, white for highlights like I thought, it's more like:
-base color
-some type of red, purple, or blue around the eyes, nose, cheeks, ears, etc
